The weight of individual fruits was practically uniform, but the 

 variation iu number of fruits and in the consequent weight of the 

 product was very marked. The date of ripening was also variable. 



Conclusion : The individual variation of plants of any given sort 

 is often such as to obscure any effects of different methods of cul- 

 ture. Results previously obtained are confirmed. 



4. Crossing : Some of our work in developing a tomato which 

 shall be of sufficient earliness to be proGtable as a market crop in 

 those sections where the seasons are short, was detailed in our last 

 annual report.* Selections and further crosses were made the 

 present season with interesting and promising results. 



The Lor illard- Peach cross showed a less marked increase over 

 the pure Lorillard, in number of fruits than was the case in the 

 first generation, — a fact which illustrates the principle frequently 

 laid down that crossing within the limits of the species tends to 

 promote fruitfulness. In the second generation the influence of 

 the male parent on the character of the fruit was shown by several 

 individuals which assumed the peculiar rough skin, and to a certain 

 extent the form of Peach.
