Exp. S. The land on wliicli this experiment was ma(.le evidently 

 needs potash, the nitrate of soda and dissolved rock plats yielding 

 almost one tlionsand cpiarts less per acre than the potash in conihina- 

 tion with nitrate of soda or than the potash alone. The small yield 

 in Experiment No. 8 was no doubt due in great part to the fact that 

 the fertilizer was received late and was not applied until August 

 before the fruiting. The succeeding crop of wheat showed that the 

 berries did not get all the fertilizer, for the wheat was much better 

 on the fertilizer plats. 



Exp. 9 represents an acre plat selected because of its known his- 

 tory, it being a rather stony pasture that had never been plowed 

 and was so poor that the owner said it was practically worthless. 

 The sod, Avhicli was very thin, was turned under early in the spring, 

 the large stones removed, the ground thoroughly fitted and planted.

33. — Stony land, before clearing for straicbernes. This land gives excellent 

 results. Experiment No. 10 teas made on this land. 



Clean cultivation was ffiven throus^hout the g-rowino; season, and a 

 mulch of straw was given in November. Unfortunately, the fer- 

 tilizer applied to Plats 5 and 6 was sown too close to the plants, 

 destroying almost every one, thus causing those plats to be left out 

 of the experiment. As would be expected from the condition of 

 the land and the further handicap of an extremely dry season 

 throughout the plant-making period, the yields on every plat were 

 very small, but the benefit of using dissolved rock may readily be 

 seen, as may also the use of manure used on Plats 1 and Y. These 

 Plats 1 and 7 made more plants, resisted the drought better and 

 were marked for the largest yield ; but the fruiting season showed 

 that Plat 9 had the material in the soil to produce not as many 

 berries as Plat 1, but nnicli larger ones.
