Surly young men in khaki union-overalls. The most energetic and vital places in town. A large warehouse for agricultural implements. An impressive barricade of green and gold wheels, of shafts and sulky seats, belonging to machinery of which Carol knew nothing potato-planters, manure-spreaders, silage-cutters, disk-harrows, breaking-plows.
The use of better seed produces larger crops, but only at the expense of the soil. Even the farm manure is so limited and is spread so thinly with manure-spreaders made for the purpose that it adds but little to the soil in comparison with the crops removed and sold in grain and hay as well as in meat and milk. Clover, as commonly produced and harvested, adds little or no nitrogen to the soil.
Dick Forrest, saluting continually his people, passed at a gallop the dairy center, which was almost a sea of buildings with batteries of silos and with litter carriers emerging on overhead tracks and automatically dumping into waiting manure-spreaders. Several times, business-looking men, college-marked, astride horses or driving carts, stopped him and conferred with him.
