_Achievements in Scientific Breeding_
In the earlier pages of this chapter we have already alluded to this fascinating subject as an ill.u.s.tration of modern efficiency in country life. Four years ago a.s.sistant Secretary Hays of the Department of Agriculture a.s.serted that scientific breeding of better stock and plant life was netting this country a billion dollars a year, of the total agricultural production of seven and a half billions in 1907.[22] In 1910 the total reached about nine billions and it is probable that scientific agriculture was the main cause of the great increase rather than additional acreage.
One of the wonders of modern science is this story of the development of new plant species and improvement in the best of the old, by the skillful processes of plant breeding. Notable also has been the improvement in American horses, cattle, swine and poultry, developed by the same scientific principles. Projected efficiency, or breeding power to beget valuable progeny, is the central idea. Simple selection is the method. Out of a large number of animals the phenomenal individual is selected for his notable capacity for reproducing in his offspring his own desirable characteristics. Thus the best blood is multiplied and the less desirable is discarded. Sometimes by close inbreeding the eugenic process has been hastened. In this way scientific stock raisers have been able practically to make to order animals with any desired quality. For instance, the great demand for bacon in England has been met by a masterly bit of agricultural statesmans.h.i.+p, for which Mr. John Dryden, chief of the Canadian Agricultural Department, is responsible. After careful study and experiment, the Yorks.h.i.+re and Tamworth breeds of hogs were crossed and a special breed developed especially valuable for bacon with exceptionally long sides of uniform thickness and with alternating layers of fat and lean. Selected bacon made to order!
New breeds of sheep have been developed which have combined phenomenal wool-producing power with superior meat production; similarly short-horn cattle with great milk-giving capacity and beef production; and more remarkable still have been the results in horse breeding. In spite of all the motor-cycles and automobiles, the horse is becoming more and more useful, because more highly civilized and specialized. The breeders know how to build up horse-flesh to suit your special needs for draft horse, family horse, trotter or pacer, with any desired form, proportions or talent, almost as accurately as a druggist compounds prescriptions! The wonderful possibilities involved challenge our imagination. Among the results of this stock-raising strategy we ought to expect not only happier and richer farmers, but better and cheaper food and clothing for all cla.s.ses of people. The very fact that the business is now on a scientific basis has appealed to students and is attracting men of large abilities who see the opportunity to better rapidly, year by year, the live-stock quality of the whole country.
_Marvels in Plant Production_
In the field of plant breeding these marvelous results are more rapid and startling because of the wider range of selection. Hybridization, the crossing of different species, has accomplished much more than simple selection. Dr. William Saunders of Canada succeeded in crossing the Ladoga and Fife varieties of wheat and secured a wheat which was earlier than Fife and yielded better than Ladoga. Likewise, Luther Burbank was able to produce a hybrid walnut by crossing the English and Black walnuts; and Webber and Swingle developed the new fruits called tangerines and citranges by crossing sweet oranges with carefully selected specimens of the wild fruit. Experiments last year in blueberry culture developed luscious berries a half inch in diameter. Possibilities in berry development are almost unlimited, especially by crossing with hardy wild varieties.
Peach raisers have two great obstacles to sure success: drought in the Southwest and frost toward the North. Science is helping them to compete successfully with the severities of nature. A hardy wild peach has been found in Northern China and grafting on this stock has produced (this last year) the hardiest peach in Iowa; while another strain bids fair to meet the drought-resisting needs of the Southwest fruit grower.
Our agricultural explorers are searching the world for new varieties which can be used in hybridizing to perfect the American species. For instance, a wild wheat has been found in Palestine which requires very little water. So a specialist in acclimatization was sent directly to the slopes of Mount Hermon to discover its possibilities for American dry farming. If the plant doctors succeed in developing wheat which can be raised in our arid wilderness, it would repay a thousand fold the expense of a round-the-world trip. The possible profits in skillful plant breeding are almost unlimited. Burbank is quoted as a.s.serting: ”The right man under favorable conditions can make one dollar yield a million dollars in plant breeding.” In 1908 the Minnesota Experiment Station had spent $40,000 in breeding the cereal grains. The agricultural department is authority for the opinion that ”the increased production is estimated at a thousand fold, or $40,000,000.”[23]
The justly famous navel oranges of California can all be traced to two scions sent from the U. S. Department of Agriculture some years ago. The Wealthy apple, which thrives in the cold north better than any other good variety, goes back to the early struggles of Peter Gideon at Lake Minnetonka, who faced the Minnesota winter almost penniless, coatless and with a family dependent upon him; but had faith enough to invest his hard-earned dollars in selected apple-seed from his far off home in Maine.
The largest single contributor to the wealth produced by scientific breeding is said to be the Burbank potato. The van-guard of American experimenters are ranging the world and bringing home large-fruited jujubes (as good as dates) from the dry fields of Central Asia; seedless Chinese persimmons which have just been successfully fruited in North Carolina; a j.a.panese salad plant and a vegetable called _udo_ which is similar to asparagus; edible roots called _aroids_ which thrive in swampy land where the potato rots; hardy alfalfa from central Asia successfully crossed with our own varieties for our cold northwest; drought-resisting cherries, apricots with sweet kernels, Caucasian peaches, olives hardy in zero temperatures, mangoes from Porto Rico, the Paradise apple which grows wild in the Caucasus, the Slew Abrikose, an apricot as smooth as the nectarine, and wild strawberries fruiting in February on the dry cliffs of western Asia which, through cross-breeding may help to carry our native strawberry many miles still farther to the north.
The story is endless; but these items suggest to us the thoroughly statesmanlike way in which our agricultural leaders are increasing year by year the possibilities of our soil in spite of all drawbacks of condition and climate. No wonder they are already prophesying that our annual agricultural production will before long reach twenty billions. When it comes, a large part of the credit must be given to the skillful agricultural scientists who are furnis.h.i.+ng all progressive farmers these newer species of plants and animals which are superseding the inferior varieties.
_Irrigation and the Problem of the Desert_
When it is the problem of sterility, it is hopeless. But usually it is merely the problem of aridity; which is only a challenge to enterprise.
Much of our ”Great American Desert,” as the old geography used to describe it, is in reality the most fertile of all soils; no wonder it can easily be made to ”blossom as the rose.”
Dr. W. E. Smythe in his fascinating book ”The Conquest of Arid America”
calls attention to the fact that the real dividing line between the east and the west is the 97th meridian which divides in twain the Dakotas, Nebraska, Kansas, Oklahoma and Texas. East of this line is the region of fairly a.s.sured rainfall. To the westward stretches the vast area of arid land with a rainfall insufficient to sustain agriculture; and with only three or four people to the square mile, though with resources enough to support a hundred million people. With a climate matchless for health and a varied and beautiful scenery, coupled with untold mineral deposits and a soil fertility that is remarkable, this great section is slowly coming to its own, through the method of irrigation, from the mountains and the streams.
With characteristic western spirit the above author remarks, ”Even in humid regions nothing is so uncertain as the time and amount of the rainfall. In the whole range of modern industry nothing is so crude, uncalculating and unscientific as the childlike dependence on the mood of the clouds for the moisture essential to the production of the staple necessities of life.” The superiority of irrigation as a certain means of water supply which can be regulated at will is a thesis easy to maintain.
The results make a marvelous story. ”The ca.n.a.l is an insurance policy against loss of crops by drought, while aridity is a substantial guarantee against injury by flood. The rich soils of the arid region produce from four to ten times as largely with irrigation, as the soil of the humid region without it. Twenty acres in the irrigated West should equal 100 acres elsewhere. Certainty, abundance, variety--all this upon an area so small as to be within the control of a single family through its own area, are the elements which compose industrial independence under irrigation.”
The small farm unit, usually from five to twenty-five acres, brings neighbors close together, abolis.h.i.+ng loneliness and most of the social ills of farm life in the East. Beautiful irrigated villages are springing up which rival in comfort and privilege most places on earth, and combine both city and country privileges, where rural and urban meet. The spirit of cooperation is strong in irrigated communities, enforced by the common dependence upon the common enterprise and water supply. This is well ill.u.s.trated by the Mormon commonwealth, the pioneer irrigators of the West.
The enthusiastic irrigating farmer a.s.serts that irrigation is ”the foundation of truly scientific agriculture.” ”The western farmer who has learned to irrigate thinks it would be quite as illogical for him to leave the watering of his potato patch to the caprice of the clouds as for the housewife to defer her wash-day until she could catch rainwater in her tubs.” Irrigation certainly furnishes the ideal method for raising a varied crop, giving each crop individual treatment, serving each of thirty varieties of plants and trees with just the amount of daily moisture they individually need, so as to produce maximum products. No wonder three crops in a year sometimes result, and sometimes five crops of alfalfa in the Southwest. Here we come to the highest development of intensive farming where the utmost value of agricultural science has free play and rivals the results of research and skill in any other line of human effort.
_Dry Farming Possibilities_
Wonderful as these irrigation projects are, we must not fail to notice that this method of reclaiming arid lands can only be used where there are mountains, rivers or water courses which can be tapped. Ultimately an area as large as New England and New York State will probably be blessed by irrigation. But this is only a small fraction of the arid West. How shall the rest be reclaimed from the desert? Obviously by some method of dry farming, depending on and conserving the meager rain-fall.
A few simple principles have been discovered, and some specialized machinery developed, by which successful dry farming is now conducted on an extensive scale along the arid plains between the Missouri river basin and the Sierra Nevada mountains. In brief these principles are: deep plowing, sub-soil packing, intensive cultivation, maintaining a fine dust mulch on the surface, the use of drought-resisting grains, especially certain varieties of wheat, allowing the land to lie fallow every other year to store moisture, and keeping a good per cent. of humus (vegetable matter) in the soil to resist evaporation. In every possible way the dry farmer conserves moisture. The dry mulch is particularly effective. Only a few years ago it was discovered that by capillary attraction much of the water absorbed by the spongy soil during a rain is lost by rapid evaporation, coming to the surface, just as oil runs up a wick. But by stirring the surface the ”capillary ducts” are broken up and the moisture tends to stay down in the sub soil; for the two inches of dust mulch on the surface acts like a blanket, protecting the precious moisture from the dry winds.
