troatmeiitsiiitratoofsodapive the poorest and muriate of potash the best 

 results. In the (h)ul)le combinations the best results were Avitli nitrate 

 of soda and boneblack. The hijihest yield was, howe\er, obtained when 

 all three of the fertilizers were used to.iiether. These results, taken in 

 connectiou with those obtained in 1800, show that nitrate of soda should 

 not be used alone for tomatoes on poor soil. 



To see whether highly improved varieties of tomatoes would res]iond 

 more readily to the application of fertilizers than small and unimproved 

 varieties, two dozen plants of Ignotura, Ithaca, and the plum tomato 

 ((lolden Fig) were set out on ])oor, hard clay loam. Half of the jdants 

 received a single application of a ''complete fertilizer'' and the other 

 half were not manured. The tabulated residts show that in the 

 improved varieties increase in the number of fruits was accompanied 

 by a decrease in the weight of individual fruits. In the unimjjrovcd 

 variety there Avas less increase in number and no loss in size of fruits, 

 so that there was a greater proportionate gain in the weight of the 

 crop. 



Kiuiy and late settinrf (pp. WJ, 150).— Plants set in the tield May 9, 

 1801, gave larger yields than those set June 10, despite the fact that 

 dry and cold weather followed the earlier planting. This agrees with 

 the results of a similar experiment in 1800. 



Few and many transplantings (pp. 150, 151). — Two series of experi- 

 ments were made. In one the plants were set in the field May 9 and 

 in the other June 10. In both cases a comparison was made of trans- 

 planting once, twice, and three times. The tabulated results show that 

 two transplan tings gave the largest yields, though in one instance three 

 transplantings gave the earliest fruits. 



Sccdn vs. cuttings (pp. 151, 152). — In 1800 seedling plants were much 

 more i)roductive than cuttings. In 1801 Lorillard plants gave a much 

 better crop from seedlings, but in the case of very poor plants of the 

 Ithaca variety the results were reversed. The cuttings in both lots 

 gave earlier fruits than the seedlings. In a single experiment where 

 cuttings were taken from cuttings of the Lorillard variety the first 

 fruits were obtained quite late, but the yield and size of the fruit were 

 much greater than in the case of the parent plants. The second cut- 

 tings made short, stocky plants with numerous branches, while the 

 first cuttings made a tall growth. 



Trimming (pp. 152-154). — Experiments in 1800 in trimming plants 

 twice (July 18 and August 25) gave increased earlincss and produc- 

 tiveness. Similar experiments were tried in 1801 on some 40 plants of 

 7 varieties. Three trimmings (August 3 and 24, and September 18) 

 were made. The results, as tabulated, show that there was increase in 

 earliness only in one case and gain in j)roductiveness only in two 

 instances. In two cases there was a decided loss. " It is therefore 

 evident that if trimming is to be done at all it must be performed 

 rather early."
