228 Experiments icitli Artificial Manure as Top-dressinr/. 



Peruvian g^uano, was distributed by the broadcast manure-drill 

 before the harrows ; the land was in poor order, and I therefore 

 put on an extra dressing. The land was ploughed before winter,

 soon as the other by some days, which was remarkable all along 

 for its difference in appearance from the rest of the field. 



No. 3. The next experiment with oats contrasts unfavourablj 

 with the above results. Perhaps guano in quantity is best 

 applied to a better description of land than mine is. Our 

 climate also tells against its application, I fancy, and the season
