lecting jars as those which are used for butterflies, as xhey are very apt to injure 

 the latter, tearing and spoiling the wings. If the collector is engaged in taking 

 other insects besides butterflies and moths, he should have special jars in which to 

 put the beetles and other hard-bodied and spiny things. 



If the collector does not wish immediately to mount his specimens, but to 

 preserve them for mounting at a future time, they may be left in the envelopes of 

 which I have spoken, or may be "papered." The simplest way of putting up 

 butterflies in papers is to take an oblong piece of any kind of moderately good pa- 

 per and fold it as indicated in the diagram (see Plate E, Fig. 6), first folding on the 

 line a-b, then on a-d and c-b; then on the lines b-f and e-a, as marked in the dia- 

 gram. The result is the enclosure of the insect as shown in Plate E, Fig. c. A 

 hundred or more of such envelopes may be put into an ordinary cigar box. Such 

 boxes, filled with butterflies, in order to prevent mould and the ravages of pests, 

 should have some chloroform or carbon bisulphide put into them and afterward a 

 spoonful or two of naphthaline crystals. Then they should be closed and sealed 

 up by pasting strips of paper over the edges. Butterflies thus collected on journeys 

 may be safely carried for long distances without injury, or even transmitted through 

 the mails provided the boxes are strong enough to resist crushing. When on 

 journeys the writer of these paragraphs always papers his specimens, bringing them 

 home to be later carefully mounted at his leisure. It is of the utmost importance
