the Colorado experiment station from wild Colorado tubers. The tubers 

 under cultivation were "quite large relatively to the other forms [samples 

 of Solanum Jamesii^, oblong in shape, and of a dark brown color." Sev- 

 eral crosses were made in Colorado upon this wild potato from pollen of 

 common potatoes, but I am not aware that any subsequent report has been 

 made upon them. The Wild Mexican potato has been grown by several 

 experimenters for a number of years. Their reports would be interesting. 



DO FERTILIZERS AFFECT THE QUALITY OF TOMATOES? 



There is much discussion concerning the supposed effects of different 

 fertilizers upon the quality — solids, sugar, acids — of tomatoes. Samples 

 of tomato fruits were taken September 6 from various fertilizer plots for 

 chemical examination. In the following table each entry or sample means 

 a single fruit. The fruits selected were well colored and of medium 

 size and ripe enough for dessert use. All the samples are Ignotum. 



Do fertilizers modify quality of tomatoes? 



The fertilizer plots from which these fruits were taken are of two series. 

 The samples 1 to y are from a general test to determine the values of 

 nitrogen, potash, and phosphorus, alone and in combination. Six plants 

 constituted a plot, and the fertilizers were sown on the surface June 20. 

 The yields of these plots are shown in Table IV, page 195, of our last 

 tomato bulletin (No. 45). 



Samples 9 to 11 are from a series of plots designed to determine the 

 relative merits of single and intermittent applications of nitrate of soda
