196 RESULTS OF EXPERIMENTS 



The quantity applied in this case was too small to yield any 

 decisive result. 



2. On oats, a In 1846 Mr Main, at Whitehill, Mid-Lothian, 

 applied it to oats after turnips, top-dressed on the 26th of 

 May: 



Grain. Straw. 



Nothing gave .... 45 bushels 24 cwt. 

 Muriate of ammonia, 2 cwt. . . 71 ^ ... 32 ... 



The larger dose applied in this experiment gave a striking 

 increase both in grain and straw. 



b In 1842 Mr M'Lintock, near Glasgow, applied it on the 

 4th of April to Blainslie oats, succeeding a crop of oats in the 

 previous year. The following table shows the results in the 

 immediate corn crop, and the after hay crop of 1843 : 



Grain. Straw. Chaff. Hay in 1843. 



Nothing gave . . 35f bush. 92 stones 304 Ib. 201 stones 

 Muriate of ammonia, 1 cwt. 45 J ... 120 ... 260... 195 ... 



3 On rye. Mr Fleming in one of his early experiments 

 obtained from a crop of rye, slightly dressed with sal-ammoniac, 

 the following result : 



Grain. Straw. 



Nothing gave . . . . 14 bushels 36^ cwt. 

 Sal-ammoniac, 20 Ib. . . . 19 ... 43| ... 



This small top-dressing produced apparently a considerable 

 effect, but the whole crop was too small to allow any confidence 

 to be placed on single results. 



4. On grass, cut for hay. 



a At Barochan, in 1846, it was applied to three different 

 fields of grass, afterwards cut for hay. The top-dressing was 

 made on the 28th and 30th of April ; horn-dust was applied at 

 the same time in comparative experiments :
