In the cultivation of flax, the land should be rendered perfectly free 

 from weeds, and made very fine, in fact completely pulverized. Guano 

 has been found a useful manure for this crop, and well rotted farm yard 

 dung in small quantities has been found to produce excellent crops of 

 this most useful plant. 



VARIOUS KINDS OF MANURE. 



Having in a former part of this essay, examined the nature of bare 

 yard dung, and explained its composition, and also produced important 

 analysis, to shov? the materials of which plants and s<^ils are coin[)osed, 

 I will proceed to notice some of the most valuable manures, omitting 

 those which are of least importance. 



Guano. 



Guano being the dung of fowl comes under the head of "animal 

 manures." It is an extremely valuable substance, and has enabled the 

 farmer to increase the extent and luxuriance of his green crops. It is a 

 great deal more portable than batn-yard dung, and tl.erefore can be used 

 in localities into which it would be impossible to bring the latter men- 

 tioned substance. 



A small quantity of guano will sometimes have an extraordinary ef- 

 fect on the soil, or rather on the crop to which it is applied. I have 

 Been an excellent crop of turnips raised by the application of 200 lbs. of 

 guano per acre; 400 lbs. per acre is the amount generally used. It is 

 a good manuie for turnips, potatoes, carrots, pai snips, beets etc., and is an 

 excellent top dressing for grain crops of every kind, and also for clovei 

 and every kind of grass. 



I have frequently used guano, and found it to be a good manure, but 

 its effects generally disappear with the crop to which it is applied. 



Some farmers liave found its good effects inoie permanent, and on
