wheat. Wheat is a self-fertilizing plant. Left to itself, it will reproduce itself throughout endless centuries. Great care is necessary in the work, and trained men are essential. As soon as the pollen is transferred—which is done about four o'clock in the morning at the hour when the wheat forets open—the head of wheat is encased in a tissue sack so that the work may not be interfered with by any pilfering insect or bird. Two of the best

The work of wheat breeding began many years ago on the great Vilmorin estate in France. M. Henri Vilmorin, carried on extensive experiments in the creation of new breeds, more than a thousand new wheats having been tested by him. I shall not forget a trip to his farms at Verrières-le-Buisson, under the guidance of the present head of the house, M. Philippe Vilmorin. Ten years ago similar work was begun at the state institution in Minnesota, not only to create new breeds of wheat but to carry them forward through a series of years until enough wheat of a superior variety should be accumulated to

last results are slowly won ; for the first harvest is very meagre, and the second and even the third are small. But after a number of years enough wheat can be garnered to sow the twentieth of an acre; and then come tangible results. To breed a new wheat requires infinite pains and patience. It has taken ten years to bring the new wheat varieties at the Minnesota Experiment Station to the farm test.

In the meantime hundreds of wheats have

been proven valueless. Some were too heavy TRANSFERRING THE POLLEN
