ively to the other forms [samples of Solanum Jamesii], oblong 

 in shape, and of a dark brown color."* Several crosses were 



made in Colorado upon this wild potato from pollen of common 

 potiitoes, but I am not aware that any subsecjuent 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 six 

 from various fertilizer plots for chemical examination.§ In the 

 following table each entry or sample means a single fruit. The 

 fruifts selected were well colored and of medium size and ripe 

 enough for dessert use. All the samples are Ignotum. 



The fertilizer plots from which these fruits were taken are of 

 two series. The samples 1 to 8 are from a general test to 

 determine the values of nitrogen, jxytash and phosphorus, alone 

 and in combinatton. Six plants constituted a plot, and the fer- 

 tilizers were sown on the surface June twenty. The yields of 

 these plots are shown in Table IV, page 269 of our 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 (Tables I, II, III, Bulletin 45). These plots con- 

 tain fifteen plants each. Samples 9 to 9c are from a plot which 

 received a single application of nitrate of soda of three pounds 

 June twenty; No. 11 received the same total amount in four 

 applications. 



Samples 12 and 12a are from a plot to which a liberal dressing 

 of good, fine stable manure was applied. 



The soil in all these plots is a fairly good, dry and high grav- 

 elly loam.
