APPENDIX, 



H aving in the foregoing Treatise made fre- 

 quent mention of the different soils necessary to 

 be used, or at least best suited, to the cultiva- 

 tion of tender Exotics, and more especially to 

 their propagation ; I mean here to give a con- 

 cise view of their nature, and a few observa- 

 tions concerning where they are generally to be 

 found, as well as the subsequent manner of 

 preparing them for use. 



Loam, peat, and sand, seem to be the three 

 simples of nature, if I may so call them, most 

 requisite for our purpose; to which, we occa- 

 sionally add as mollifiers, vegetable mould, and 

 well rotted dung ; from the judicious mixture 

 and preparation of which, composts may be 

 made to suit plants introduced from any quar- 

 ter of the globe : but for propagation, I always 

 prefer them in their simple state, particularly 

 Loam, and Sand, in either of which when pro- 

 perly handled, I find the cuttings of most known 

 species to vegetate more freely, than in any other 

 compost whatever.
