received no inamire. The results are snmnmrizfd in four tables. The 

 largest yields were obtained when the full ration of potash was used. 



Cabbages (pp. 29-31). — Tabulated data are giveu for some 30 varieties 

 planted late iu the spring. 



Tomatoes (pp. 32-37). — Tests of varieties and experiments with fer- 

 tilizers are reported. 



Tomatoes, tests of varieties. — Tabulated data for 32 varieties, and brief 

 descriptive notes on the 10 most productive varieties, viz., Horsford's 

 Prelude, Cumberland Red, Essex Hybrid, Golden Queen, Ignotum, 

 Optimus, Puritan, Red Cross, and Table Queen. 



Tomatoes, fertilizer experiment. — Nitrate of soda, cotton-seed meal, 

 muriate of potash and superphosphate (mixed minerals), and the min- 

 erals in combination with different amounts of either nitrate of soda or 

 cottonseed meal, were used on seven plats, and one i)lat received no 

 manure. The results, as tabulated, indicated that— 



(1) The application of nitrogen alone gave no increase over the unfertilized plat; 

 (2) minerals produced a marked increase ; (3) nitrogen in single ration in combina- 

 tion with mixed minerals showed a decided gain over mixed minerals alone; (4) the 

 largest yield was attained by the application of double rations of nitrogen and mixed 

 minerals; (5) the effect of nitrogen depends upon the presence of the mineral ele- 

 ments, jihosphate and potash ; (6) earliness is in proportion to the elfectiveness of 

 the fertilizer. 



Peas (pp. 37-40). — Tabulated data for 27 early and 16 late varieties. 



Beans (p. 41). — Tabulated data for 30 varieties. 



List of fruits planted at the station ml890 (pp. 43-45). — This includes 

 47 varieties of apples, G of cherries, 14 of figs, 42 of peaches, 36 of pears, 

 26 of plums, 5 of quinces, 48 of grapes, 13 of blackberries, 14 of rasp- 

 berries, and 51 of strawberries.

Field experiments with corn, G. E, Morrow, M. A., and T. 

 F. Hunt, B. S. (pp. 389-432).— This article gives a detailed account 

 of experiments with corn in 1890, together with a summary of the 

 results of similar experiments in 1888 and 1889, which were recorded 

 in Bulletins Nos. 4 and 8 of the station (See Experiment Station 

 Record, Vol. I, p. 28, and Vol. II, p. 14). The following subjects were 

 treated: test of varieties; time of planting; depth and thickness of 

 planting; planting in hills or drills; frequency and depth of cultiva- 

 tion; root growth; effect of root pruning and of fertilizers; rotation of 

 corn, oats, and timothy or clover, or both ; and rotation of corn and 

 oats comj)ared with continuous cropping with corn. 



These experiments were made on a black losmi about 20 inches deep, underlaid 

 with yellow clay — the soil common to the prairies of Central Illinois. Apparently 

 the plats were notably uniform, and admirably adapted to field experimentation.
