The Manner of obtaining the Parts of a Shoot 



separate. 



In the beginning of April, take a quantif y of young branches 

 from the fcarlet oak, and other trees. Thefe are firft cut into 

 lengths, of the growth of different feafons • and then part are left 

 entire, part fpht, and the reft quartered, in tikis Mate they are 

 put into a wicker bafket, with large openings, or of loofe work, 

 and a heavy {tone is put in with them : a rope is tied to the han- 

 dle of the bafket, and it is thrown into a b^ook of running water: 

 at times it is taken up, and expofed a little to the air ; it is fre- 

 quently fhook about under water, to wafh off filth ; and once in 

 ten days the flicks are examined. 



By degrees the parts loofeo from one another ; and by gentle 

 rubbing in a bafon of water, juft warmed, they will be fo far 

 feparated, that a pencil brufh will perfect the bufinefs, and afford 

 pieces of various fize, pure, dijlincl, and clean. One part will 

 in this way feparate at one time, and another at another ; but by 

 returning the flicks to the water, and repeating the operation, 

 in the courfe of four or five weeks, every part may be obtained 

 diftinct. They are be ft examined immediately ; but if any one 

 willies to preferve them for repeated inquiries, it may be done in 

 ♦ this manner : diflblve half an ounce of alum in two quarts of 

 water; drop the pieces thus feparated, for a few moments, into 

 this folution, then dry them upon paper, and put them up in 

 4 vials
