man, Great Devonshire Street, Bishopsgate Street, 

 London. Two boards are requisite^ of the same size as 



the 



the other for the bottom of the 



mass of papers. Some pieces of pasteboard (or millboard) 

 placed between the Sj^acimens^ if these are nuinerons or 

 particularly thick and woody^ are yery usefuL For 

 pressure nothing is better than a heavy w^eight on the 

 topmost board, or, while travelling, three leathiern straps 



transversely, and 



ather your speci 



and buckles, two to bind the board ;^ 



one longitudinally. Thus provided, 



r^^ns, if the plant be small, root and stem ; if large, take 



off portions of the branches, a foot or rather mure in 



length, always selecting those which are slender and in 



flower, or in a more or less advanced stp^^^ of fruit. 



Loijg, slender plants, as grasses^ sedges^ and maiiyjfera^-, 



may be doubled once or twice. Place them, as quickly 

 after being gathered as you can, side by side, but never 



one upon the other, on the same sheet of paper, takin 



care that one part be not materially thicker than the 

 other, iMi(l lay over the specimens one, two, thi 



^ee, or more 



sheets of paper, according to the thickness of your paper 

 and of your plants ; and so on, layer above layer of paper 

 and specimens, subjecting them to pressure. In a day or 

 two, according to the more or less succulent nature of 

 the plants and the heat and dryness of the soil and 



climate, remove them into fresh papers, twice or oftener 



- r 



till the moisture be absorbed, and dry the spar<^ papers in 

 the sun or by a fire for future use. 



If the specimens cannot be laid down as soon as 

 gathered, they should be deposited in a tin box, wl 



lich 



indeed is essential to the botanist when travellin
