Photo by Westgate Although alfalfa was brought by the Persians into Greece 490 B. C., there was scarcely an acre in this country sixty years ago. Today it is considered the best rough forage known, and there are over 7,500,000 acres of it in the Western Hemisphere. The search for hardier, drought-resistant, winter-growing, better-stooling, heavier-yielding varieties has taken explor ers all over the world, and this search has attracted the attention of millions of people. As a result there are now in the Great Plains region breeding plots like the above, where are gathered together for the purpose of cross-breeding and selection the principal alfalfas of the world. The creation of entirely new forms, combining new characteristics, has already begun, and the effects will be as surely felt by this gigantic industry as good mining has felt the discovery of the cyanide process.

These plants are either growing now in some part of the United States or have been discarded by some specialist who, after having tested them, has decided that they are not yet on the program.
