Art. II. Directions for draining Trees and Botanical Specimens

 useful to all persons who feel inclined to favour us with drawings, 

 as well as to others who wish to improve themselves, to throw 

 together the following directions. They have been acted on for 

 all the trees and botanical specimens engraved or to be engraved 

 for the Arboretum Britannicum. 



Provide an octavo leaf, or several, say a dozen, of the same

 of a small oblong book. Form a parallelogram on the first page, 

 of such dimensions as to include the largest drawing which an 

 octavo page will admit of, and next mark the scale on the
