Trees, Fruits and Flowers of Minnesota Part 28

Mr. Cashman: We do not put anything over the tree.

Mr. Stakman: What does your oil cost?

Mr. Cashman: About eight or nine cents a gallon.

Prof. Hansen: Just a thought occurred to me that out west on the Pacific coast where men have to get down to business in order to raise fruit they have these horticultural commissioners that have absolute police power to make orchard men clean up. They will come into your old orchard and pull it up and burn it and add it to your taxes, charge it up to you, if you don't clean up. The same sort of police power should prevail here. If a man has an old plum orchard that is diseased through and through, it won't do for him to tell his tale of woe year after year and not do anything. A county agent will come along and clean it up for him.

After it is cleaned up it will be an easier proposition. If you are not going to keep up with the times and spray, then the county agent ought to have police power to burn the orchard. Either spray or go out of the plum business.

TO MAKE CONCENTRATED APPLE CIDER ON A COMMERCIAL SCALE.--The specialists of the fruit and vegetable utilization laboratory of the department have completed arrangements for a commercial test of the recently discovered method of concentrating apple cider by freezing and centrifugal methods. As a result, a cider mill in the Hood River Valley, Ore., will this fall undertake to manufacture and put on the retail market 1,000 gallons of concentrated cider, which will represent 5,000 gallons of ordinary apple cider with only the water removed.

The new method, it is believed, makes possible the concentrating of cider in such a way that it will keep better than raw cider, and also be so reduced in bulk that it can be shipped profitably long distances from the apple growing regions. The old attempts to concentrate cider by boiling have been failures because heat destroys the delicate flavor of cider. Under the new method nothing is taken from the cider but the water, and the resultant product is a thick liquid which contains all the apple-juice products and which can be restored to excellent sweet cider by the simple addition of four parts of water. The shippers and consumers, therefore, avoid paying freight on the water in ordinary cider. In addition, the product, when properly barreled, because of its higher amount of sugar, keeps better than raw cider, which quickly turns to vinegar.

The process, as described by the department's specialists, consists of freezing ordinary cider solid. The cider ice is then crushed and put into centrifugal machines such as are used in making cane sugar. When the cider ice is whirled rapidly the concentrated juice is thrown off and collected. The water remains in the machine as ice.

At ordinary household refrigerator temperatures this syrup-like cider will keep perfectly for a month or six weeks, and if kept at low temperatures in cold storage will keep for prolonged periods. At ordinary house temperatures it, of course, will keep a shorter time.

To make the concentrated syrup, the cider mill must add to its equipment an ice-making machine and centrifugal machinery, so that the process is not practicable on a small scale. The specialists are hopeful, however, that the commercial test soon to be inaugurated in Oregon will show that it will be possible for apple growers to concentrate their excess cider and ship it profitably to the far South or to other non-producing regions. The specialists also believe that it will enable apple producers to prolong the market for cider.--U.S. Dept. of Agri., Oct., 1914.

How Mr. Mansfield Grows Tomatoes.

MRS. JENNIE STAGER, SAUK RAPIDS.

Somewhere around 1870 Mr. Wm. Mansfield, of Johnsons Creek, Wis., commenced to apply what Gov. h.o.a.rd, of Wisconsin, told him was "persevering intelligence," to the propagating and improving of the tomato, and he soon found out that the tomato was capable of almost unlimited improvement. He has made a specialty of the tree tomato, of which he says he has demonstrated to the world that in the Mansfield tree tomato he has produced one of the greatest wonders of the age. All who have seen them, tasted or grown them, with even a small degree of good sense, are loud in their praise for their good qualities: wonderful growth of tree, beauty of fruit, smoothness, solidity, flavor, earliness, etc.

In giving directions how to grow them he says you should remember that if your brightest child is raised among Indians he is not likely to become president. Neither will the tree tomato if thrown on a brush pile, or just stuck in a poor, dry place and left to care for itself, be ready to jump on your table, on the Fourth of July, or any other month, a ripe, delicious, two-pound tomato.

He says first get your seed of some reliable person, who can warrant it pure and all right. Then at the proper time, which in this climate would be some time in March, get some rich old earth for boxes in your house, hotbeds or greenhouse. Sow the seed, cover lightly, wet down every day and keep warm, with all the sun possible. When up ten days transplant to other boxes, six inches apart, and not less than four inches deep. Keep wet and give all the light and sun you can, and by the time it is safe to set them outside they should stand from twelve to twenty-four inches in height, with bodies half an inch thick.

_To prepare the ground._--First select a place as near water as possible, and also, if you can, let your rows run east and west. Throw out dirt two spades deep, then put in three or four inches of night soil if you can get it, if not use hen manure and wood ashes, equal parts, or some other strong manure, in the bottom of trench. Then fill up the trench with the best dirt you can get, mixed with well rotted stable manure, as no fresh manure must come near the roots or bark to rot them.

Now set out your plants without disturbing the dirt about the roots. Set eighteen inches apart in the row and have the dirt in the trenches a little lower than at the sides. Place a strong stake at each plant or a trellis and tie them to it as fast as set. Then if it does not rain use hard, soft, cold or warm water and give plenty each day. As your plants commence to grow, just above each leaf will start a shoot. Let only the top of the plant, and only one or two of the best branches grow, so as to have not over one or two of the best stems to run up. Now the buds for blossoms show themselves on the tops of the vines, and a few inches below. Just above each leaf, a shoot starts; nip off every one of these just as soon as they appear. As the lower leaves get brown and old pick them off. Train the fruit as it grows to the sun. Tie often and well.

Let no useless wood grow. Give all the sun possible and water, water and then water. Then you can take the cake on tomatoes.

Mr. Mansfield's record twenty-six years ago, at Johnsons Creek, Wis., was: Height of tomato tree, eleven feet. Weight of single tomato, two pounds six ounces. He says, since he has moved to North Dakota, his tomato has in no wise deteriorated.

Annual Report, 1915, Central Trial Station.

PROFS. LE ROY CADY AND R. WELLINGTON, UNIVERSITY FARM.

Since the coming of Prof. Wellington to the Station to take up the pomological and vegetable divisions the work of this Station, has been divided, Prof. Wellington taking the fruit and vegetable experimental work, while Prof. Cady continues the work in ornamentals, and on that basis the reports will be made this year.

_Ornamentals._--The campus of University Farm has been very much enlarged this year by the building of the Gymnasium, and consequent parking about it, and the grading of an athletic field. This will call for considerable planting work next spring.

The season has been exceptionally good for the growth of all ornamental stock. All came through last winter in good shape. A late frost killed many of the early flowering plants, and this prevented the forming of fruit on such plants as barberry and wahoo. About 400 seedling paeonies flowered again this year. Some of these are promising. An excellent block of aquilegia was flowered. A trial ground of some hundred or more annuals was maintained and proved very interesting. It is hoped that many more annual novelties may be tried out this year. The perennial garden established last year was added to and furnished something of interest the whole season. It will be the aim of the Division to have in this garden all the annuals and perennials of value in this section.

Some new shrubs were added by purchase and through the Bureau of Plant Industry. The hedges have proved an interesting exhibit again this year, and it is planned to add a number of new ones to the group next season.

About seventy-five varieties of chrysanthemums were flowered this autumn and were much enjoyed by our visitors.

_Fruit._--This year has been a very poor fruit year owing to the freeze on May 18, when the thermometer dropped to 26 degrees Fahrenheit. At that time a very promising crop of apples was frozen on the trees.

Currants and gooseberries were also frozen on the bushes, and the young shoots were frozen on the grape vines. Later the grape vines sent out secondary shoots which bore a small crop of late maturing fruit.

Regardless of the heavy freeze an apple was found here and there throughout the orchard, although no one variety seemed to be particularly favored. On one-year-old Compa.s.s and Dyehouse cherry trees a few fruits were borne, and a similar amount of fruit was produced on one-year-old Sapa and Skuya plums. The old plum seedling orchard, which is located to the south of the college buildings and is partially protected by a wooded hill to the north, gave about five per cent of a crop. The one-year-old raspberries and blackberries bore a small crop, and the new strawberry bed, containing over 150 varieties, yielded a good crop. Records were made on the blossoming dates of practically all the varieties grown at the Station, and complete descriptions were made of all the strawberry flowers, fruits and plants.

[Ill.u.s.tration: Cla.s.s in propagation at work at Minnesota State Agricultural College.]

Plants were taken from the strawberry bed and used for setting out a new bed, which is located on level and uniform ground. By another year sufficient data should be at hand to report on the performance of the varieties tested.

The aphids were very numerous and unfortunately caused the defoliation of all the currants with the exception of the blacks. A new sidewalk through the currant patch necessitated the transplanting of about one-half of the varieties, and so the prospect for a good currant crop next season is poor. The mildew attacked the Poorman gooseberry very severely but did practically no damage to the native varieties, as the Carrie and Houghton. Blight was a negligible factor, and what little appeared was removed as soon as noted. This year's rest, especially as it has been coupled with a good growing season, should be very favorable for an abundant crop in 1916.

In summing up the varieties at the Trial Station, it is of interest to note that the following number are under observation: 235 apple, 1 apricot, 15 cherry, 3 peach, 6 pear, 70 plum, 23 blackberry, 3 dewberry, 14 red currant, 3 black currant, 2 white currant, 13 gooseberry, 26 grape, 4 black raspberry, 22 red raspberry, 1 purple raspberry and 157 strawberry.

_Vegetables._--The vegetable work has been concentrated on the bean, cuc.u.mber, lettuce, pea, onion, potato and tomato. The chief work with the bean and pea has been to isolate desirable canning types from the present varieties. Selection has also been carried on with the lettuce, with the object of securing a head type which matures uniformly. Onion bulbs of various types have self-fertilized, and desirable fixed strains will be separated if possible. Incidentally, the inheritance of various types and colors of the onion is under observation. In the tomato the influence of crossing on yield and earliness has been studied. Increases nearly as high as five tons have been obtained, and the prospects are very bright for securing valuable combinations for gardeners who use greenhouses and high-priced land. Results of this work will probably soon be published in a station bulletin.

[Ill.u.s.tration: Chrysanthemums in flower in University Farm greenhouses.]

A better type of greenhouse cuc.u.mber is being sought by combining the European and White Spine varieties. From past experience the author knows that a uniform type that is well adapted to market purposes can be obtained, and the only question will be its productiveness.

Unfortunately hybridizing was not performed early enough in the season, and disease prevented the making of crosses. This coming season the work will be repeated.

The main work of the year has been on the potato, and the chief problem has been on the determination of the cause of degeneracy. Incidentally, many varieties have been tested, and the exchange of seed with the Grand Rapids, Crookston and Duluth stations has been started. If possible, the effect of varying climatic and soil conditions on the potato will be noted.

A few vegetable varieties have been tested and among them the Reading Giant, a rust-proof asparagus, has proved promising. Malcolm, the earliest Canadian sweet corn, ripened very early and will be tested further. Washington, a late sweet corn ripening between Crosby and Evergreen, made an exceptionally good showing and may prove of much value for market purposes. The Alacrity tomato was found to be similar to the Earliana and superior in no way. Bonny Best and John Baer tomatoes produced smooth, desirable fruit and are deserving of a wide test.

The much advertised "seed tape" was given a trial, and it proved satisfactory in most cases. For kitchen gardeners who are ignorant of planting distances, methods of planting and varieties, and who can afford to pay a higher price for their seed, the tape may prove of value, that is, if a high grade of seed is maintained.

A CORRECTION.--In O. W. Moore's interesting article on "s.e.xuality in Plants," which appeared in the November (1915) number of The Horticulturist, two errors were present. The first is merely typographical, as Kaelreuter's name, page 411, should be spelled Kolreuter. The second, however, is misleading, as it states that the process of fertilization is called "Mendel's Law." It is true that Mendel's Law is based upon fertilization, but it concerns simply the splitting up of certain characters into definite mathematical proportions. For example, Mendel found that when he crossed a yellow and green pea the first generation produced only yellow peas. These peas when self-fertilized split up into practically three yellows to one green. By self-fertilizing the progeny of the second generation it was found that one-third of the yellows bred true for yellow, and two-thirds of the yellows broke up into yellow and green, showing that they were in a heterozygous condition, and that all the greens bred true for green.

At the present time this method of segregation has been proved to hold for many easily differentiated characters in both the animal and plant kingdom, but much more experimental work will have to be done before it can be said to hold for all inheritable characters.--Prof. Richard Wellington, University Farm.
