little pains with them. They will never again be as firm and easily 

 placed, and if the above directions about not allowing them to move 

 afterwards are followed, it will be found that every minute so employed 

 will save many at the second handling. Still there is a limit of econ- 

 omy in this, and in many cases it is fully as well to pay no further

attention to the specimens than to see that they are snugly inclosed in 

 the folds of the book. No end should, under any circumstances, be 

 allowed to project. Whatever portion does so is sure to be ruined ; for, 

 in the first place, it is exposed to the air and sun and dries up, and, in 

 the second place, it is certain to rub against bushes and other objects 

 and be torn and bruised. The specimeijS must go wholly inside the 

 portfolio. This suggests a remark upon specimens longer than the 

 book they are to be placed in. How is this to be done ? If only a little 

 less than twice the length, a bend in the middle is the thing required. 

 But do not guess at the middle ; place the full-length plant upon the 

 book; see that one end clears by at least an inch ; then bend the stem 

 over your finger an inch from the other end. If the stem is tough 

 and wiry and refuses to remain in position after it has been bent, a 

 piece of paper with a slit, as shown in Fig. G, may be put over the end.
