FERTILIZERS. 



R. H. ALLEN & CO., keep constantly on hand, the following popular Fertilizers, 

 each of which, they guarantee to be pure, and the best of their kind : 



E. F. COB'S Super-Phosphate of Lime. This is composed wholly of bones, 

 either raw, or such as have been charred and used by the sugar refiners. They are 

 thoroughly decomposed by the addition of Sulphuric Acid, which is itself a fertilizer, 

 and when the charred bone is used, the ammonia-forming material of the bone, (the 

 animal tissues,) which had been expelled by heat, is fully made up by adding ammo- 

 nia. It is applied to crops in drills, or by sowing broadcast, and harrowing lightly 

 in. There will be no injury to seeds or plants, if placed in contact with them. 



Ground Hone. This is one of the most economical manures, and like the Super- 

 phosphate, is applicable to all soils, and to all the muscle and bone-forming plants, 

 grains, roots, &c. It may be sown broadcast, or in drills. 



Flour of Done, is pure bone, reduced to fine powder, and is applied to all crops, 

 as above. 



Number One Peruvian Guano, (and we keep no other quality,) is the most 

 concentrated, and hitherto, has been considered the most desirable of the commer- 

 cial manures. Its principal value is in its ammonia, of which it contains 8 to 16 per 

 cent. It also contains about 25 per cent, of phosphate of lime and magnesia, which, 

 however, may be much more economically provided by either of the foregoing fer- 

 tilizers. Other manures, containing the mineral constituents of plants, such as 

 potash, soda, the phosphates of lime, magnesia, &c., (which are always found abun- 

 dantly in all forms of bone manures, and in ashes, barn yard manures, &c.,) must be 

 added with Peruvian Guano, or the crops will soon exhaust the soil of these neces- 

 sary ingredients, in consequence of the excessively stimulating effects of the ammo- 

 nia, which the Peruvian Guano holds in so large a proportion. It is furnished in bags 

 of about 160 Ibs. each. 



Phosnix Guano is one of the best of the Phosphatic Guanos from the Pacific 

 Ocean, which are generally or commercially, known as AMERICAN GUANO. The 

 origin of this guano is identical with the Peruvian, being the deposits from the 

 innumerable flocks of sea-birds, which have resorted for ages to those islands of the 

 Pacific, where these deposits exist. But in all these islands, the abundant rains 

 (which never occur on the Chincha Islands where the Peruvian is found,) have 

 washed out the more volatile and readily soluble ammonia, leaving over 50 per cent, of 

 bone, phosphate of lime, and other fertilizing salts. In consequence of the absence of 

 ammonia, its effects on crops, though more enduring, are not so immediate, as from 

 the application of the Peruvian guano. 



Ammoniated Pacific Guano. This is a manufactured article, the basis of 

 which is the Phosphatic Guanos from the Pacific Ocean, with the addition of ammo- 

 nia producing ingredients, such as animal matters, and particularly the residium of 

 fish, after expelling the oil. The slow decay of this animal matter in the soil, forms 

 ammonia, the beneficial effects of which, add materially to its value as a fertilizer. 



Fish Guano, is composed exclusively of the remains of fish, (which are caught 

 in great abundance on our Atlantic coast,) after expelling the oil, and thoroughly 

 drying and grinding. 



All of the above, except Peruvian Guano, are shipped in barrels of 200 to 275 Ibs. 

 each.
