SOLON ROBINSON, 1850 377 



1st. Plowed in 250 lbs. 7 inches deep on corn land, and 

 harrowed in wheat, and sowed one bushel plaster to acre 

 on surface of part. 



2d. After the land was plowed, mixed guano, wheat, 

 and plaster, and sowed and harrowed. 



3d. Land plowed, and wheat, guano, and plaster sowed 

 and plowed in 2 or 3 inches deep. 



4th. Guano and plaster plowed in five inches and 

 wheat harrowed in. 



The quantity and quality all equal. The present ap- 

 pearance, (April 26th,) is decidedly in favor of the first 

 part of first experiment. 



From all that I can learn, I am convinced that the best 

 application that can be made is 200 lbs. Peruvian guano 

 to the acre, plowed in deep, [How "deep," one inch, five, 

 ten or twenty? — Eds.,] and that it is the most beneficial 

 upon sandy loam, and pays the greatest profit upon lands 

 so worn out as to be absolutely worthless for cultivation. 



Col. Robert W. Carter,^ of Sabine Hall, Richmond 

 county, Virginia, a gentleman noted as one of the most 

 improving agriculturist upon the northern neck, after 

 thoroughly testing the various manures in various ways, 

 has become so thoroughly convinced of its value, and the 

 bad economy of ever sowing wheat without using it, has 

 ordered 40 tons of Peruvian guano for his fall seeding of 

 1850. He plows it in deep. 



No part of the United States is using guano to the ex- 

 tent it will be used next fall, in this part of Virginia. I 

 have notes of a great many other experiments, and shall 

 continue to take others for publication for the encourage- 

 ment of any who may be timid about buying this most 

 wonderful and most profitable fertiliser. R.
