On well-manured grass- land, alongside, the yields varied from 8,960 pounds to 4,480 pounds during the same period. Mismanaged land does proportionately worse in unfavorable years when produce is high. In other words, land in good condition gives more uniform yields and the good farmer is more independent of seasonal variations than the poor farmer. By intense cultivation and heavy fertilizing and seeding, Mr. George M. Clark, of Higganum, Con- necticut, reports enormous yields of hay (Fig. 660). He says : " Last year (1906) my timothy and red-top field contained eleven acres, and the alfalfa field three and one-half acres. The eleven-acre field produced in two crops eighty-one tons of well-dried hay, and the three-and-one-half-acre field produced twenty- one tons in four crops, making one hundred and two tons from the fourteen and one-half acres. The seven - eighths - acre piece is a part of the eleven-acre field, and produced its usual crop of over eight tons, in two crops, each year, or one hundred and forty-seven tons in seventeen years, at one ; (3) The number and character of the plants per acre. Although it is not known how much empha- sis can be laid on these factors, it is conceivable that they are of some importance. It is certain that an animal must not have to travel too far to secure its food if we would have it fatten, and that a certain number of plants must be maintained per acre for profit. As to the character of the plants necessary for a good pasture, there is little data. Investigations conducted in the United Kingdom, by Drs. Fream and Carruthers, for the Royal A
