time there teas little rain, and, in consequence, it burned the pl.a7its, of which they did not re- 

 cover all the season, and the ground got full of weeds. No. 5 burned the plants also, but 

 they recovered quickly, and gave a good return. Asicas remarked he/ore, icherever cvrnmon 

 salt was put on as a top dressing on grain crops, either oficheat, barley, or oats, and on what- 

 ever description of soil upon this estate, the grain was invariably heavier per bushel, and had 

 fewer weuks or tails in proportiu7i to the quantity of grain per acre, than any of the other 

 dressings apj)lied here. From the frequent mention of spade culture in these experiments, 

 many may consider that they were upon a very small scale, which is not the case, the 

 greater proportion of Ihem being very extensive. Mr. Fleming, to give employment to the 

 destitute labourers, having dug and trenched about thirty acres of land instead of ploughing 

 it, which accounts for the frequent mention of spade culture, which, when it can be got ex- 

 ecuted at a moderate rate (particularly trenching at j£4. oer acre), is very advantageous, 

 and seems superior to trench ploughing. • A. F. Gardiner. 



D.— EXPERIMENTS UPON OATS. 



The first of the following series of experiments was made at Lennox-Love, 

 at the request of Lord Blantyre, the second at Barochan, under the direction 

 of Mr. Fleming. The general object of both was the same — to ascertain the 

 relative effect of different salnie siibsta7ices applied as top-dressings vpan young 

 oats; but those of Mr, Fleming have, besides, t/ie special object of ascertaining the 

 effect of certain mixtures upon oats token grown upon mossy land. 

 1°. Oats, second crop, after old lea. Soil sharp loam ; subsoil clay resting on sand-stone 

 rock. Oats sown 14th March; top-dres.sings applied 13th May ; crop cut 27th Aug. ; and 

 thrashed 9th Sept. , 1842. The gtiantity of land in each plot was one-eighth of an imperial acre.
