EXPERIMENTS UPON WHEAT.

F.— EXPERIMENTS UPON PASTURE AND OTHER GRASSES. 



I. Experiments made by Mr. Alexander, at Wellwood, in 1842. 



A. On crops of meadow and rye grass hay. 



\°. One Scots acre of well-drained mossy meadow, and full of timothy grass, 

 was top-dressed during the last week of April, with 1 cwt. improved bones, \ 

 cwt. glauber salts, \ cwt of charcoal, all well mixed with ashes. Result. — 

 Crop much improved, and came to 180 Ayrshire stones (of 24 lbs.) per acre. 

 I may mention that this meadow suffered generally much from the severe 

 drought ; the above kept its growth best. 



2°. One- Scots acre of well-drained mossy meadow, full of timothy grass, was 

 toprdressed dming the last week of April, with 1 cwt. of artificial guano, 12 

 bushels of humus, well mixed with a quantity of ashes. Result. — Not so 

 good; more affected by drought;, crop 160 stones per acre ; the rest of the un- 

 dressed meadow land, on an average, 140 stones per acre. 



3°. Three acres of rye grass hay, upon a very light sharp soil, was top-dressed 

 during the last week of April, with 3 cwt. of artificial guano, 2 J cwt. of improved 

 bones, 1 cwt. of charcoal, all mixed with a quantity of ashes. Result. — I can- 

 riot pronounce that the hay on the three acres was increased in bulk ; the crop 

 was a light one on the whole field, owing to the severe drought, and the very 

 dry nature of the soil this season, therefore, gave this experiment no fair trial. 

 I would say, however, that I have rarely seen such an appearance of white 

 clover since the hay was cut, and particularly on the dressed land,
