The relative decline in fruit size from primary to secondary to tertiary positions on the inflorescence of large-fruited clones was much greater than for small-fruited clones. Large-fruited clones produced fruit with more achenes and larger achenes than did small-fruited clones. Fruit weight was positively correlated with total achenes per fruit, developed achenes per fruit, mean weight of total and developed achenes, and fruit weight per developed achene. These results lead to the conclusion that fruit size differences among strawberry clones are due to the combined effects of developed achene number, developed achene size, differential activity of achenes in producing growth hormones and differential sensitivity of receptacular tissue in responding to growth hormones.

Wild rice {Zizania aquatica) i.s still an important, if not the chief, farinaceous food for probably 30,000 of the American aborigines, notably the Ojibwas. It is the principal fattening-agent too for myriads of wild fowl in the eastern half of the United States. It is now being placed on the market in a small wa}^as a breakfast food.On account of its great value as a food for game birds it has been widely and justly recommended as a suitable plant for shallow lakes and sluggish streams which are maintained as shooting-preserves.The seed has been extensively marketed, but in most cases with results unsatisfactory to the buyer, for usually it fails to germinate.So nearly universal was the difficulty that some seedsmen who did not wish to disappoint their customers refused to handle the seed, or sold it only in small quantities. For a time it was supposed that the loss of vitality was due to the scorching to which the seed was subjected when gathered for food by the Indians, but it was found that seeds which had never been scorched failed also to germinate. It was then determined to try a series of experiments based on the observation that the grain of wild rice is still somewhat soft and moist at maturity and falls into the water immediately without hardening.These experiments, which are recorded in this report, show that the way to preserve the vitalit} T of the seed is to keep it from becoming thoroughly dry, at the same time aerating it sufficiently to prevent molding. The practical course suggested to buyers is to place their orders before the time of the wild rice harvest, have the seed shipped immediately on maturitj^, and sow it at once. The observations and experiments were delegated to two investigators, Mr. Carl S. Scofield, who made an examination of the plant in its natural situation in Minnesota, and Mr. Edgar Brown, who conducted the storage and g-ermination tests.
