acid phosphates, 200 Ibs. to the acre, and alongside the same 

 number of Ibs. of a dissolved bone, of high grade, and at the end 

 of the year came to the conclusion that they are about equal 

 in value. This conclusion comes from the fact that the acid 

 phosphate was enough, or, in other words, had sufficient availa- 

 ble phosphoric acid and sulphate of lime, while the other con- 

 tained more than was wanted, and the excess was not taken 

 up 'by the plant, but remained in the soil, where it is true it 

 would not be lost, but remain the valuable property of the 

 owner of the soil. 



As our capitals are short we are not able to make such large 

 investments, and should only buy, pay for, and apply what will 

 be returned to us in the crops of this year. It is true that high 

 manuring will pay, but equally true that it will only pay when 

 followed by a high state of cultivation and deep ploughing, etc : 

 and, even then, it is not certain to pay, except on lands that 

 have been brought up for some years past, and which are in a 

 high state of cultivation, in farming language well in heart 

 well educated lands. 



For the ordinary field crops of cotton, from 75 to 150 Ibs. of 

 a high grade manipulated Fertilizer will pay a better divi- 

 dend on the money invested than will 200 Ibs. A bale of cot- 

 ton requires only about fourteen Ibs. of phosphoric acid and 

 about eighteen Ibs. of potash to make it. A 24 per cent, dissolved 

 bone will yield eleven Ibs. per 100 of phosphoric acid, and we can 

 always trust the soil to supply some ; hence, until all the other 

 ingredients of the soil, the seasons, etc., are sufficient to pro- 

 duce over one bale per acre, 100 Ibs, will be found enough for 

 common plantation use, and especially for the common field 

 cultivation in vogue amongst us. Practical farmers will find 

 150 Ibs., perhaps, the best quantity to apply. 



It will be best to concentrate your cotton seed and stable 

 manure, supplying ammonia, on your poorer lands, and to use 

 the Dissolved Bone on your fresh and improved lands. To 

 aid the inexperienced, we give below a table for six different 

 soils. 



No. 1 represents very poor and exhausted lands ; Nos. 2 and 

 3 better grades ; No. 4 a good old land, capable of producing 

 or growing a cotton stalk, without any fertilizer, eighteen to
