Tlie small seeded varieties " are better suited to thin or moderately- 

 fertilized soils, since tliey make smaller drafts on the soil; while the 

 1 iiger boiled, larger seeded varieties are perhaps better adapted for 

 high culture, for strong or liberally manured soils." 



Distance experiments (pp. 200-202). — In rows 4 ft. apart single stalks 

 were left at distances of 1, 2, 3, and 4 ft. Both on the plats liberally fer- 

 tilized and on the unfertilized plats the largest yield was made at dis- 

 tances of 1 by 4 feet. The following table gives the yields of seed cot- 

 ton at each of these distances for each of the years during which the 

 experiment has been in progress : 



Yield of seed cotton at different distances. 



The author advises early planting when it is intended to give each 

 stalk ample distance, and close planting as the northern limit of the 

 cotton belt is approached. 



Effect of increaning amount of fertilizer (pp. 202-204). — In this experi- 

 ment a complete fertilizer was applied at the rate of 400, 800, and 

 1,200 lbs. per acre, and the results were compared with those secured on 

 unfertilized plats. With the variety King the use of 400 lbs. of fertil- 

 izer resulted in a profit of 71 per cent on the investment for fertilizers; 

 for the variety Jones Improved, 14 per cent. Using 800 lbs. of fertil- 

 izer there was a profit of 11 per cent with King, but a loss of 8 per 

 cent with Jones Improved. Twelve hundred pounds of fertilizer 

 resulted in a financial loss with both varieties. 



General fertilizer experiments (pp. 205-207). — In 1894 the formula giv- 

 ing best results consisted of 408 lbs. of acid phosphate, 54.6 lbs. of mur- 

 iate of potash, and 130 lbs. of nitrate of soda, and the mixture contained 

 10 per cent available phosphoric acid, 4 per cent potash, and 3 per 

 cent nitrogen. With none of the fertilizer mixtures was there any con- 

 siderable profit. 



Green manuring with cowpeas (pp. 207-209). — Cowpeas planted after 

 oats in 1893 were plowed under (1) green, or (2) after the peas had been 

 picked, or (3) the stubble was plowed under, the vines being made into 

 hay. The results agree with those of previous years in showing that 

 the greatest profit (taking into consideration the value of the cotton 

 crop of 1894 and the value of the cowpeas and hay in 1893) was 

 obtained by making hay of the vines and plowing under the stubble. 



Florida soft phosphate vs. superphosphate (pp. 209, 210). — Superphos- 

 phate in a complete fertilizer was compared with an equal amount and
