great cost, It Is to the farmer a matter of the last moment, to 

 procure a supply at the cheapest rate, the greatest amount of 

 efficient vegetable nutriment at the least expense. With this 

 object various foreign substances have more recently been 

 resorted to, »mong the more prominent of which, may be 

 mentioned crushed bones and Peruvian guano. Both these 

 articles have for some time been extensively used in England as 

 fertilizers, and more recently in some parts of this country, as in 

 Virginia, Maryland, and North Carolina where guano has been 

 largely applied and with great efficacy. In New England the use 

 cf these and like substances for manure, has been more limited, 

 but of both guano and crushed bones in a crude state, or 

 dissolved in sulphuric acid, is beginning to excite attention. It 

 has been supposed that our climate was too dry to render the 

 application of guano successful, but this objection if well founded, 

 may generally be obviated by seizing a proper time to apply it 

 to the land early in spring, when rains usually are of frequent 

 occurrence, or at other times when there are indications of 

 showers.. I have myself used guano as a top-dressing to grass 

 -lands, and both guano and dissolved bones for other purposes, 

 with, as I thought, decided success, and so far as a limited 

 experience justifies the formation or expression of an opinion, 

 am inclined to think that both, the latter as manufactured under 

 the name of the improved superphosphate of lime, as fertihzers 

 are worthy the attention of Farmers. Although the cost of such 

 a quantity as is usually considered sufficient for an acre, say 400 

 to 500 lbs, amounting from $10 to $12 50 is an item to be 

 considered, yet if more than repaid by the produce of the first 

 crop, it will be a not injudicious expenditure, and taking into view 

 the fact that, it can be applied to the land without the expense of 

 carting or handling, attending the application of the substances 

 commonly used for the purpose, it is believed that guano will 

 prove cheaper than any other manure the farmer may be required 

 to purchase. 



Another objection that has been made to the use of guano as a
