It will be observed that there is but little differ- 

 ence in the chemical composition of these import- 

 ant elements, except that of lime, which, in the 

 peach, is largely developed. All these ingredients 

 are familiar to every tiller of the soil as manures, 

 and are applied almost yearly to crops. With this 

 analysis before us, we have no need of inquiry of 

 our neighbor as to the kind of manure best adapted 

 to the orchard. We see that these three fruits are 

 composed largely of potash, lime and phosphate of 

 lime, and when the soil becomes exhausted of either, 

 or all, and the ground begins to present the appear- 

 ance of poverty, as indicated in the crop, these ele- 

 ments must be resupplied to restore the trees, or 

 rather to continue their growth and vigor. 



In medium soils an application of taustic or quick- 

 lime, direct from the kiln, at the rate of fifty bushels- 

 to the acre, spread on the plowed ground, and well 

 harrowed in, as for corn, is about all the manuring 

 or treatment that the ground requires for the peacb 

 tree at planting, and for the first season of its- 

 growth, with the usual attention in cultivating the 

 corn, potatoes or other cultivated crops which may 

 occupy the ground. As caustic lime always cheap 

 and accessible is to act a leading part in the new 

 programme, as a remedial agent for the protection
