Trees, Fruits and Flowers of Minnesota Part 59

If lime-sulphur is determined upon, the home-made article may be used, or the commercial lime-sulphur solutions may be used, in which case they should be diluted with water, in the proportion of one gallon of the commercial lime-sulphur to not more than ten gallons of water. The application should be made thoroughly, so that every bit of the bark of trunk and limbs is covered with the spray.

If miscible oil is used, I would recommend using one gallon of the oil to each nineteen gallons of water. Hard or alkaline waters should be avoided, as sometimes the oil will not make a good emulsion with them.

Use soft water, if possible.--C.P. Gillette, Colorado Agricultural Experiment Station.

Some of the promises regarding our future stagger us with their vastness. "To him that overcometh will I grant to sit with me on my throne." But how is it down here? Thou "crownest him with riches and honor." Thou hast "put all things under his feet." Unto fields where feet of angels come not we are chosen as partners of the Heavenly Father to make this a more fruitful and beautiful world.

In our life work much depends on our att.i.tude regarding our calling. We can plod like an ox, or like Markham's semi-brute man with the hoe, and make that the badge of servitude to toil, or we can make it a wand in a magician's hand to call forth radiant forms of beauty from the somber earth to smile upon us and load the air with fragrance. We can live down in the bas.e.m.e.nt of horticulture or in the upper story.

Man is coming to his own. The savage trembled at the lightning stroke which shivered the mighty oak. Little knew he that here was a giant at play waiting to be tamed and harnessed so he could be the most obedient servant--ready at the master's beck to leap a continent, dive under the ocean, draw heavy trains, and run acres of machinery. Man reaches out his wand, and steam, gas, and oil rise up to do his will.

If, with the advance of civilization, he wants beautiful things to adorn person or home, he finds subterranean gardens of precious gems almost priceless in value--gems that are immortals, flowers that never fade, prophets all of the "glory to be revealed."

You have heard of the marvelous Persian garden of gems--four hundred feet in length and ninety feet wide--made to imitate the most beautiful blooms of earth. It cost millions upon millions. Do you know that it is in your power, with the advance of floriculture, to create gardens far more resplendent in beauty--great gardens of delight fit for the touch of angel's feet, while the whole is flooded with billows of sweetest perfume? Three years ago that was a patch of barren earth; now you have pulled down a section of paradise upon it and condensed there the tints of the morning, the splendors of the evening, the beauty of the rainbow, and the effulgence which flames in the mantles of the suns.

I love to think of Nature as a person--first born daughter of G.o.d--her head white with the snows of the centuries, her cheeks radiant with the flush of recurrent springtime, emblems of eternal youth. She takes you by the hand, leads you into the forests, talks to you of the soul of the tree, tells you how intelligent it is. There is one standing in the open. It has performed a feat no civil engineer can emulate. Think of those roots so busily scurrying around in the earth, gathering food to send up the cambium highway to nourish the trees. See the taut cords thrown out to anchor it against the storms. Look at those trees on the outskirts. Among wild animals the strongest are on guard on the outside to protect the herd. So these sentinel trees guard their wards against the storms. Fool man cuts down the guards and the wards fall before the sweep of the storm. Mother Nature--dear, friendly soul--takes you into her holy of holies and reveals her mysteries. She makes a confident of you. She throws open her doors and shows you the wide vistas of a new land you may enter and glorify. Follow her direction, and what a friend you have! Cross her, thinking you know more than she does, and she laughs at you. She takes you into the garden and the nursery and discloses her wonders and helps you to work miracles. You plant seeds and bulbs, and beauty rises to greet you. Did you ever think of the royal position of the florist and horticulturist?

The sacred poet speaks of the "labor of the olive." What a flood of light that opens upon us. "All things are yours." Let us go out into the grove you have planted. I once took off my hat to myself. While living in the Republican Valley, near the 100th meridian, I planted some bull pine seed. When the little trees were large enough, I transplanted them in rows six feet apart and started a miniature forest. Twenty-five years after I went to see them. The rows were straight. The trees had fine bodies six inches through. They were miniature columns in a temple, holding up a canopy of green. The ground was covered with a thick carpet of needles. It was one of the most pleasing sights I ever saw. Then I thought, "What if I had planted forty acres?" I would have had a Mecca to which horticultural pilgrims would have flocked from hundreds of miles. I planted the trees, and the faithful servants kept on working day and night, and that beautiful grove was the result. Every tree you plant is your servant, and how faithful it is--no shirking, always at it whether you are looking or not. Look at that cherry tree. How the tiny rootlets scurry through the soil--faithful children gathering food to send up to their mother. Look at that flood of bloom. Then the fruit grows till a ma.s.s of red gleams from the leafy coverts. There is a great difference between a patch of brown earth and your faithful Jonathan.

What a marvel that little patch of soil, absolutely milked by those busy foragers, and the extracts of it glowing in red beauty on the tree. Talk of chemists! Those quiet rootlets surpa.s.s them all.

[Ill.u.s.tration: Albert Victor iris, from Mr. Harrison's garden--about one-third size.]

If you want to be in the realm of miracles, lay down your hoe awhile and sit among your flowers. Your brain devised the plan, your hand planted the seeds and bulbs. "Behold the lilies, how they grow." Now sit there and think it out. At your feet are artists no human skill may imitate.

Two peonies grow side by side. Golden Harvest opens with yellow petals fading to purest white. In the center is a miniature Festiva Maxima--blood drops and all. How can those roots send up the golden tints, the snowy white and the red, and never have the colors mixed?

Close by is a Plutarch, deep brilliant red. The roots intermingle. How is it possible to pick out of the dull soil, Nature's eternal drab, that brilliant color for your peony? There are your iris, the new sorts absolutely undescribable. There are a dozen different shades in a single bloom. But those blind artists at work in their subterranean studios never make a mistake. The standards must have just such colors, the falls just such tints, and where did they get that dazzling radiant reflex such as you see on Perfection, Monsignor and Black Knight? But it is always there shimmering in the sunlight. There is a fairy--a pure snowy queen. How was that sweetness and purity ever extracted from the scentless soil? Every bloom uncorks a vial of perfume which has the odor of the peach blossom.

Did you ever sit down in your kingdom and see what a royal throne you occupied? What a reception your flowers give you! The ambrosia and nectar of the feasts of the deities of fable are overshadowed by the fragrance and sweetness of your worshippers. It would seem that every flower, like a royal subject, was bent on rendering the most exalted honor to her king. No company of maidens preparing for nuptials were ever arrayed like these. Each one is striving to do her best. The highest art ever displayed in the palaces of kings is no comparison to the beauty and splendor of your reception. By divine right you are supreme. The fertile soil puts her tributes at your feet; for you all the viewless influences of nature are at work; for you the sun shines and the showers fall. So brothers, don't creep but mount up as on eagle's wings. Invoice yourself and see how great you are! Don't live all the while in the bas.e.m.e.nt--spend some time in the upper story of your calling!

You are not making the earth weep blood. You are not spreading on the fields a carpet of mangled forms. You are not dropping ruin and death from the skies or polluting G.o.d's pure waters with submarines. You are not turning all your energies into the work of destruction, despoiling the treasures of art and the pride of the ages and turning the fairest portions of the earth into desolations. You are not changing yourselves into demons to gloat over starvation and ruin. You are soldiers of peace. Behind you was the somber earth. You touched it with the wand of your power, and beauty, health and pleasure sprang up to bless you.

See what you have done! You have clothed the barrenness of the dreary plain with gardens, orchards and forests. You have been at work with G.o.d and glorified a vast empire, and now he has blessed the work of your hands. Instead of the air sodden with tears and tremulous with the wail of widows and orphans, you are welcomed with the joy of children and the delight of mothers. All along the lines of progress you receive the most cordial ovations, and when you pa.s.s on to the land where "everlasting spring abides", may you receive the royal welcome, "Well done, good and faithful servant."

The Newer Fruits in 1915 and How Secured.

PROF. N. E. HANSEN, STATE COLLEGE, BROOKINGS, SOUTH DAKOTA.

Mr. Hansen: Mr. President and Fellow Members: This subject is not an entirely satisfactory one this year owing to the fact that we lost about three sets of tomato plants from frost, the last frost coming the ninth of June. These conditions, of course, are unusual, but it prevented the fruiting of a lot of new fruit seedlings which appeared promising.

However, I decided to propagate two new plums because they had borne several excellent crops. One of these is a very late plum of good quality, with flesh of peculiar crisp texture, which ripens after all the other plums, about a week before frost. It is a combination of the Wolf plum with the Kansas sand plum (_Prunus Watsoni_). The tree is of late dwarf habit but very productive, and its late season may give it a place.

Another plum which I decided to place in propagation is a hybrid of the wild plum of Manitoba with the j.a.panese plum. The mother tree was raised from wild plum pits received from Manitoba a few years ago. These bear very freely and are the earliest of the native plums. The tree is of low, dwarf habit. The fruit is not as large as my Waneta, which is a hybrid of the largest native plum, the Terry, (_Prunus Americana_), with the Apple, one of the best of Burbank's j.a.panese plums. But since the range of the plum Manitoba is so far north, it may give greater hardiness where that is needed. At any rate, it is of interest to know that the Manitoba native plum can be mated with the j.a.panese plum.

Pears const.i.tute my favorite line at present. "What can I do for hardy pears?" is a question I have been asked many times. The prairie northwest cannot raise pears owing to the cold or the blight. In my travels in Asia, including four tours of exploration in Siberia, I made a business of buying up basketfuls of pears in Manchuria, Mongolia, Western China and Eastern Siberia and saving the seed, giving the flesh away to the coolies, who were glad always to get the fruit. These have raised me many seedlings. In addition I have imported a lot of pears from Russia.

[Ill.u.s.tration: Pyrus Simoni

The hardy, blight-proof sand pear used by Prof. N.E. Hansen in breeding pears for the Northwest. A careful study of our eastern Arctic pears has been made recently by Mr. Alfred Rehder, botanist at Arnold Arboretum, and this form of sand pear is now called Pyrus Ovoidea instead of Pyrus Sinensis, or Pyrus Simoni.]

The pears of northern China and eastern Siberia are usually called the Chinese sand pear and have been given various names, _Pyrus Sinensis_, _Pyrus Ussuriensis_, _Pyrus Simoni_. The form I am working with mainly was received in the spring of 1899 at the South Dakota Station under the name of _Pyrus Simoni_, from Dr. C.S. Sargent, Director of the Arnold Arboretum, Boston, Ma.s.sachusetts. Since the publication of Bulletin 159, of the South Dakota Experiment Station, April, 1915, in which I give a brief outline of this work, the pears of this region have been studied by Dr. Alfred Rehder of the Arnold Arboretum, and it now appears that the true name of _Pyrus Simonii_ should be _Pyrus Ovoidea_. These trees have proved perfectly hardy at Brookings and have never suffered from blight. Varieties of other pears have been top-grafted on this tree, and they have blighted, but the blight did not affect the rest of the tree.

Mr. Charles G. Patten, Charles City, Iowa, also has a form of the Chinese sand pear which has proven immune to blight. In other places sand pears have been under trial which have suffered from winter-killing. However, I understand that the pear Mr. Patten has tapers toward the stem, while the pear received by me as _Pyrus Simonii_ tapers toward the blossom end. The actual source of seed is really of greater importance than the botanical name, as it is possible to get the seed from too far south, whereas we should plant only the northern form of the species.

The fruits of _Pyrus Ovoidea_ correspond in size to the ordinary pear much like the Whitney crab-apple does to the apple. It is a real pear, juicy and sweet, but not high flavored. Other varieties of pears have been top-grafted on this tree and have blighted, but the blight did not affect the rest of the tree. During the many seasons I have had this pear the tip of one twig only showed a very slight trace the past season, but I did not determine it was really blight. It is practically immune.

I have also worked the Birch-Leaved pear, _Pyrus betulifolia_, Bunge, a native of northern China, and a choice ornamental tree. Trees of this species were received from a nursery in Germany in the fall of 1896 and have proven perfectly hardy and quite resistant to blight. The fruit is quite small, usually less than one-half inch in diameter, covered with thick russet. _Betulifolia_ means birch-leaved, alluding to the shape of the leaf.

Now, the pear is a difficult thing to work with on account of blight.

What is blight? It is an American bacterial disease, not found in the home of the pear, Asia or Europe, so that during the 6,000 years of its cultivation of recorded history the pear has never had to meet the bacterial enemy known as blight. That is one of the reasons, I presume, why they have such strict quarantine in Europe against American trees.

The question with pears is, will they stand blight or not? They are spending hundreds of thousands of dollars in California to keep out blight. Blight is a native of the northeast United States, and they are keeping it down on the Pacific slope, but they are always on the edge of the precipice. The whole pear culture of America is in an unsatisfactory state, owing to this danger.

With these two northern pears as a foundation, I have endeavored to secure seedlings with fruit of large size and choice quality by hybridizing them with many of the best cultivated pears from Germany, France, England, Central Russia and Finland, as well as with some of the best varieties from the eastern pear-growing regions of the United States. The work has been done mostly under gla.s.s in our fruit-breeding greenhouse. Some of these fruits weighed one and one-fourth pounds. Some of the resulting seedlings are subject to blight, while many have thus far shown immunity. Since it is impossible to determine their relative immunity to blight except by distributing them for trial elsewhere, I sent out scions in the spring of 1915 of thirty-nine of these new seedlings to twenty-four men in several states. These varieties are under restrictions until fruited and deemed worthy of further propagation.

[Ill.u.s.tration: Crossing work in pears--view in Prof. N. E. Hansen's Fruit-Breeding Greenhouse, State College, Brookings, S.D.]

I did not know whether immunity to blight is a possibility or only an iridescent dream, so I made no charge for these scions. The only test of a pear seedling, the same as with the apple, is that of propagation.

Furthermore, if you have but the one seedling tree you may lose it by accident; whereas, if you send it out to a number of good men, you cannot lose it.

It should be distinctly understood that none of these new seedlings have borne fruit, but by what may be termed the projective efficiency of the pedigree I am satisfied that some of them will be valuable. In like manner, a horse-breeder depends so much on the pedigree in his colts that he is willing to enter them in a race. I believe something of value will come from this line of work. I do know that my _Pyrus Ovoidea_ is a pretty good, juicy little pear, a whole lot better than no pear at all.

I hope these seedlings will keep up their immunity to blight. The original seedling trees certainly have had every chance to become affected by blight, as they were surrounded by blighting apple trees, crab-apple trees and pear trees, and no blight was cut out. I thought this was the best way, since that is the test they will have in the farmers' orchards when they go out from the nursery.

_Hardy Pear Stocks._--Now we are up against the problem of stocks for these hardy pears. The quince is a standard dwarf stock, but it is not hardy enough for us. Last spring I planted 12,000 seedlings of the various commercial pear stocks, including imported French pear seedlings, American grown French pear seedlings, Kieffer pear seedlings and j.a.pan pear seedlings. From one season's experience I like the j.a.pan pear the best. The French pear seedlings, especially, did not do well.

The j.a.pan pear stock is coming into high favor in recent years on our Pacific slope, where it is sometimes called the Chinese blight-proof stock. The French pear stock is not in favor on our Pacific slope owing to their liability to blight. We may also expect from the French pear stock a decided lack of hardiness. The j.a.pan pear stock is probably some form of the Chinese sand pear. The seed may come from too far south, whereas we should plant only the northern form of the species. This varying degree of hardiness in the j.a.pan pear seedling of commerce I find discussed in a German horticultural paper. I have tried to establish a regular source of supply by importing the seed, but it is difficult indeed to do this. To avoid root-killing at the north we should mulch these j.a.pan pear seedlings heavily until we get enough orchards of this truly hardy form, _Pyrus Ovoidea_, planted so we can raise our own stocks. I firmly believe we will extend pear culture on the North American continent clear to the Arctic Circle if we wish.

For pear stocks I am going to try everything I can think of. Some years ago I worked pears on Juneberry stock from a hint given me many years ago by Professor J.L. Budd. These grew well and were in full bloom when five feet high, but were lost in clearing off a block of trees. I hope to try this again on a larger scale. The mountain ash and hawthorn are sometimes used, but both will be expensive and perhaps short-lived. The quince is the dwarf stock of commerce but would need to be very heavily mulched to prevent root-killing. Such dwarf pears are splendid in the back yard, or for training up against the side of the house; the fruit is fine and large, and the trees fruit the second year. The pear will root in nursery by grafting with a long scion on apple seedlings. I hope there will be much work done along this line.

To sum up the question, I think there is a hardy pear in sight. We have the requisite pedigree back of it, and it seems that the quality we call immunity to blight is in some of these Chinese or Siberian pears. If we can combine the hardiness and blight-resistance of this Siberian pear with the large size and high quality of fruit of the European pear, with thousands of years of cultivation back of it, then we have the solution of the pear question in sight. Millions and millions of people are watching for a good hardy pear. (Applause.)

WARNING TO MUSHROOM GROWERS.--As the result of a serious case of mushroom poisoning in a mushroom grower's family recently, the mushroom specialists of the U.S. Department of Agriculture have issued a warning to commercial and other growers of mushrooms to regard with suspicion any abnormal mushrooms which appear in their beds. It seems that occasionally sporadic forms appear in mushroom beds, persist for a day or two, and then disappear. These are generally manure-inhabiting species and may be observed shortly after the beds have been cased. In the instance cited, however, these fungi appeared in considerable numbers at the time the edible _Agaricus campestris_ should have been ready for the market, and the dealer supposed it was probably a new brown variety and tried it in his own family. As a result, five persons were rendered absolutely helpless and were saved after several hours only through the a.s.sistance of a second physician who had had experience with this type of poisoning.

In the opinion of the Department, this case is peculiarly significant and demonstrates that the grower must be able to distinguish _Agaricus campestris_ from any of the wild forms of mushrooms that may appear in the beds. Under the circ.u.mstances, the Department strongly urges every grower to make himself thoroughly familiar with the cultivated species.

Complete descriptions, with pictures of poisonous and cultivated species, are contained in Department Bulletin 175, "Mushrooms and Other Common Fungi," which can be purchased for 30 cents from the Superintendent of Doc.u.ments, Government Printing Office, Washington, D.C.
