withheld were perfect seeds formed. (2) The amount of pollen 

 supplied was found to have an important bearing on the form 

 and size as well as the quantity of fruit produced. The form 

 and size of tomato fruits was found to be directly dependent 

 upon the amount of pollen furnished — a small amount invari- 

 ably resulting in small and deformed fruit. (3) Indications 

 point to the possibility of distinct effects from two male parents 

 when pollen is applied to the same stigma at different times. 



EXPERIMENTS WITH THE TOMATO. 



With the tomato the following questions were considered : 

 Effect of early setting in the field ; effect of trimming the vines ; 

 effect of bagging the fruit to induce early ripening ; the effect 

 of crossing; the cumulative effect of culture under glass. 

 Results: It was found that a chill to tomato plants after set- 

 ting is not necessarily fatal to success, and that, other things 

 being equal, the earliness and productiveness of tomatoes are in 

 <lirect ratio with the earliness of setting in the field. Trimming 

 the plants, after a part of the fruit had set, increased the yield 

 by more than one-third. The results from bagging the fruit 

 were in general of a negative character. Crossing between small 

 fruited plants of prolific habit and the ordinary large fruited 

 type was found to be a promising method of securing a valuable 

 type for localities where the season is short. The increase in 

 yield of the Lorillard-peach cross over that of the pure Lorillard 

 was nearly 50 per cent. A derivative hybrid between Lorillard 

 and currant produced a type of special excellence for forcing. 

 In some instances seed from plants grown under glass gave 

 tetter results in house culture than did seed of the same variety 

 grown in the field. Results were not uniform, however, and 

 there appeared to be distinct varietal differences. 



STUDIES WITH THE CABBAGE. 



Cabbage studies included investigations as to the importance 

 of deep setting of the plants ; the effect of frequent handling; the 

 ■effect of trimming at the time of setting. Results: Contrary to 

 the general notion concerning the treatment of "leggy" plants, 

 :it was found that depth of setting had very little influence upon
