Three Acres and Liberty Part 27

As a subst.i.tute for the potato of commerce the "Dasheen" long ago pa.s.sed the experimental stage. It has been served at a number of banquets in Washington, Philadelphia, and New York.

While the tops of potatoes are useless as food, the tops of the dasheen make delicious greens, and tests indicate that good growers can depend on a crop of from four hundred to four hundred and fifty bushels per acre.

The Udo is the plant intended by the Department of Agriculture as a subst.i.tute for asparagus, a delicacy which it closely resembles. It is more prolific than asparagus, grows in the same soil, and requires less attention.

Not only plants but animals are experimented with by Uncle Sam's experts. Officials of the Bureau of Animal Industry claim that before long we will partake of antelope steak. For the antelope has been found to be particularly adapted to the more arid western sections of the country. And beyond that the gastronomist of the future will have to reckon with loin of hippopotamus!

The lower valley of the Mississippi is admirably suited to these huge beasts, the flesh of one of which equals a score of cattle.

African traveled epicures maintain that hippopotamus steak is as tender and inviting as the choicest beef. "For those who like that sort of thing, it is just the sort of thing they would like."

It seems a bit remote to urge hippopotamus on us who do not yet know enough to eat sharks, tortoises, painted turtles, or even English sparrows. Anyhow the small gardener is more likely to succeed raising pheasants than to muss with a hippopotamus, at least in the suburbs. Pigs are more practical and make prettier pets.

Our population bids fair to approximate two hundred million within the next fifty years, and, because of the exigencies of business, an increasing number of people will be engaged in non-food-producing vocations. These people, however, are all consumers and must be fed and clothed, and even now America offers the greatest market for the produce of the farm that any farmer in any country has ever had in all history.

One of the coming ways of feeding them is the discovery and use of new foods. As in other things, after the war, whether we live in a better world or not, we shall live in an entirely different world, new ways, strange thoughts, and other foods. For the most of the following, _Business America_ and _Current Opinion_ are responsible.

For the creation of new crop varieties or the improvement of those now in use we must depend upon the practical scientists who are engaged in plant breeding. The work of one of these, Professor Buffum, has been accomplished in a region that is apparently sterile and where plants grow only by coaxing through artificial moisture.

His plant-breeding farms near Worland in the Big Horn Basin of Northern Wyoming lie at an elevation of 4000 feet, in a region of almost total natural aridity.

After twenty years' work in Western agricultural colleges and Government Experiment Stations, Professor Buffum chose his present location because nowhere in the United States could he find conditions of soil and climate that induce to such a remarkable degree the breaking up of species, and mutation or "sporting" of plants.

When the modern plant breeder seeks to produce something new by cross-fertilization a problem is encountered. For many years we were ignorant of the principle upon which nature operated in these hybrids or crosses. Finally a Bohemian priest named Mendel discovered the law. The central principle is that when the seed produced from a cross between two different species is planted, the progeny breaks up into well-defined groups. A certain percentage of the plants resemble one of the parents, a smaller percentage are like the other parent, and the rest seem to be a blend of both parents. These intermediates will not breed true to themselves, however; if seed from them is planted the progeny will split up into groups, showing the same percentages as the first generation to which they belonged. This has been generally accepted by scientists.

In many of his productions Professor Buffum apparently has set the Mendelian law at defiance, for, by cross-fertilization, he has evolved plants which breed true to themselves, and their progeny does not break up into groups, according to the accepted theory.

They show specimens resembling each parent, with the third composed of seemingly, but not really, blended specimens.

These results are particularly vital in the development of plants adapted by selection for semi-arid agriculture. The Professor believes that the great areas of high plain country to be found from Canada to Mexico can be made more productive through planting crop varieties that have been bred to withstand the existing conditions which produce meagre returns from the vast expanse of territory under the present methods.

In place of corn, which is difficult to mature even at moderate elevations, Professor Buffum has introduced improved emmers and the various hybrids resulting from crosses with other grains.

Emmer itself is not a new grain, having been grown for centuries in Russia and southern Europe, and it is believed to have been the corn of Pliny, which he said was used by the Latins for several centuries before they knew how to make bread.

Several years ago emmer began receiving attention as a stock food.

The first planting of the grain at Worland resulted in some exceptional "sports," seemingly of a different type, with coa.r.s.e straw and very large heads. With this as a basis, the seed was replanted and subjected to many experiments to increase its drouth and winter resisting qualities. Continued selections have shown, a yield of from a third more to twice as much as corn, that it is thirty per cent more valuable than oats for feeding horses, and that for stock fattening it is equal to corn, pound for pound. It is the most drouth-resistant and prolific of small grains, has been successfully raised from Montana to Mexico, and is being planted in Louisiana to replace oats because it is not affected by rust.

Some of the yields recorded are enormous, varying from 40 to 104 bushels per acre under dry farming, and as high as 152 bushels under irrigation.

One stalk of Turkey red wheat was noticed as differing in many ways from all varieties, princ.i.p.ally that the head was over eight inches in length, whereas the ordinary Turkey red wheat commonly used in the West has a head of only four or five inches.

From this one stalk has been developed the Buffum No. 17 Winter wheat. The heavy beards were eliminated and the grains or kernels in each spikelet increased from the normal number of three to five, seven, and even nine. The hardiness of the new variety, together with its remarkably large head, means that when it is placed on the market the farmers who sow it need not fear winter killing and will have a splendid flouring grain, which will produce nearly double the average crop per acre.

It is said that if a single kernel could be added to each head of wheat, the increase in annual production of this country would amount to over fifteen million bushels.

If fodder crops can be subst.i.tuted for a part of the corn now used for stock, it will be a great gain.

In his alfalfa-breeding garden, Professor Buffum is raising over seventy different kinds, gathered from all parts of the world, showing that the plant is capable of wide variations. One hybrid has been obtained by crossing sweet clover with alfalfa; the clover grows wild in every state in the Union.

There seems to be no limit to man's ingenuity and skill in plant improvement. Perhaps sometime we will try it with our children.

In thirty years an exceptional ear of dent corn, through continued planting and careful selection each succeeding season, resulted in a few days' shortening of the growing period and an increased resistance to the cool nights of the higher elevation where it was under improvement; to-day, this corn matures about the middle of August at an alt.i.tude of 4000 feet, and has been yielding forty to sixty bushels per acre.

CHAPTER XXV

DRIED TRUCK

As a war measure the surplus vegetables in many city markets have been forced by the governments into large munic.i.p.al drying plants.

Community driers have been established in the trucking regions and even itinerant drying machines have been sent from farm to farm drying the vegetables which otherwise would have gone to waste.

The drying of vegetables may seem strange to the present generation, but we are very young; to our grandmothers it was no novelty. Many housewives even to-day prefer dried sweet corn to the canned, and find also that dried pumpkin and squash are excellent for pie making. Snap beans often are strung on threads and dried above the stove. Cherries and raspberries still are dried on bits of bark for use instead of raisins.

This country is producing large quant.i.ties of perishable foods every year, which should be saved for storage, canned, or properly dried.

Drying is not a panacea for the waste evil, nor should it take the place of storing or canning to any considerable extent where proper storage facilities are available or tin cans or gla.s.s jars can be obtained cheap.

For the farmer's wife the new methods of canning are probably better than sun drying, which requires a somewhat longer time. But dried material can be stored in receptacles which cannot be used for canning. Then, too, canned fruit and vegetables freeze and cannot be shipped as conveniently--in winter. Dried vegetables can be compacted and shipped or stored with a minimum of risk. String them up to the ceiling of the storeroom or attic.

A few apples or sweet potatoes or peas or even a single turnip can be dried and saved. Even when very small quant.i.ties are dried at a time, a quant.i.ty sufficient for a meal will soon be secured. Small lots of dried vegetables, such as cabbage, carrots, turnips, potatoes, and onions, can be combined to advantage for soups and stews.

In general, most fruits or vegetables, to be dried quickly, must first be shredded or cut into slices, because many are too large to dry quickly, or have skins the purpose of which is to prevent drying out. If the air applied at first is too hot, the cut surfaces of the sliced fruits or vegetables become hard, or scorched, covering the juicy interior so that it will not dry. Generally it is not desirable that the temperature in drying should go above 140 deg to 150 deg F., and it is better to keep it well below this point. Insects and insect eggs are killed by the heat.

It is important to know the degree of heat in the drier, and this cannot be determined accurately except by a thermometer. Inexpensive oven thermometers can be found on the market, or an ordinary chemical thermometer can be suspended in the drier.

Drying of certain products can be completed in some driers within two or three hours. When sufficiently done they should be so dry that water cannot be pressed out of the freshly cut pieces, they should not show any of the natural grain of the fruit on being broken, and yet not be so dry as to snap or crackle. They should be leathery and pliable.

When freshly cut fruits or vegetables are spread out they immediately begin to evaporate moisture into the air, and if in a closed box will very soon saturate the air with moisture. This will slow down the rate of drying and lead to the formation of molds. If a current of dry air is blown over them continually, the water in them will evaporate steadily until they are dry and crisp. Certain products, especially raspberries, should not be dried hard, because if too much moisture is removed from them they will not resume their original form when soaked in water.

The rotary hand slicer is adapted for use on a very wide range of material. Don't slice your hand with it.

From an eighth to a quarter of an inch is a fair thickness for most of the common vegetables to be sliced. To secure fine quality, much depends upon having the vegetables absolutely fresh, young, tender, and perfectly clean; one decayed root may flavor several kettles of soup if the slices from it are scattered through a batch of material. High-grade "root" vegetables can only be made from peeled roots.

Blanching consists of plunging the vegetables into boiling water for a short time. Use a wire basket or cheesecloth bag for this. After blanching as many minutes as is needed, drain well and remove the surface moisture from vegetables by placing them between two towels or by exposing them to the sun and air for a short time.

A mosquito net is thrown over the product to protect the slices from flies and other insects. Fruits and vegetables, when dried in the sun, generally are spread on large trays of uniform size which can be stacked one on top of the other and protected from rain by covers made of oilcloth, canvas, or roofing paper.

A very cheap tray can be made of lath three fourths of an inch thick and 2 inches wide, which form the sides and ends of a box, and smoothed lath which is nailed on to form the bottom. As builders'

laths are 4 feet long, these lath trays are most economical of material when made 4 feet in length.

A cheap and very satisfactory drier for use over the kitchen stove can be made by any handy man of small-mesh galvanized-wire netting and laths or strips of wood about 1/2 inch thick and 2 inches wide. By using two laths nailed together the framework can be stiffened and larger trays made if desirable. This form can be suspended from the ceiling over the kitchen range or over a clear burning oil, gasoline, or gas stove, and it will utilize the hot air which rises during the cooking hour. It can be raised out of the way or swung to one side by a pulley or by a crane made of lath. When the stove is required for cooking, the frame is lowered or swung back to utilize the heat which otherwise would be wasted. Still another home drier is the cookstove oven. Bits of food, left overs, especially sweet corn, can be dried on plates in a very slow oven or on the back of the cookstove and saved for winter use.

Where the electric "juice" is not monopolized, an electric fan in drying is economical, especially for those who already have a fan.

Many sliced fruits placed in long trays 3 by 1 foot and stacked in two tiers, end to end, before an electric fan can be dried within twenty-four hours. Some require much less time. For instance, sliced string beans and shredded sweet potatoes will dry before a fan running at a moderate speed within a few hours.

The dried fruit or vegetables must be protected from insects and rodents, also from the outside moisture, and will keep best in a cool, dry, well-ventilated place. In the more humid regions, moisture-tight containers should be used. If a small amount of dried product is put in each receptacle, just enough for one or two meals, it will not be necessary to open a large container.
