plan, succulent plants will often become mouldy. When thev 

 are perfectly dry, the next object is to arrange them properly 

 To do this, each one, or perhaps more, if small enough, and 

 belonging to the same genus, should be fastened to a half sheet 

 of good white paper, by loops of paper, or by stitching them down 

 with a needle and fine thread. The ends of the leaves, oranv 

 thin part which will not lie flat without, may be touched witha" 

 little glue or gum Arabic. The name of the species should be 

 written near the specimen, with any remarks as to its peculiar!, 

 ties, the place where, and time when it was gathered, or some 

 other interesting circumstances connected with it. Let all the 

 specimens of the same genus, be then enclosed in a sheet of 

 different colored paper, with the generic name, and the names 

 of all the species collected, written on the outside. The aene- 

 ra should then be arranged in their proper orders, (this sun. 

 poses that the Natural arrangement is the one adopted,) those of 

 each order being wrapped in a larger sheet, on which should 

 be written the names of the order and of the genera. The 

 orders may then be laid on the shelves of a cabinet, or in any 

 other proper place. The collector should also take care to pro- 

 tect his specimens from the attacks of insects, and for this 

 purpose, each one should be washed with a solution of cam- 

 phor, or a piece or two of camphor gum, or sponge mois- 

 tened with oil of turpentine, be placed among them. Large 

 seeds or fruit, sections or branches of wood, and other such 

 articles, which are too bulky to be pressed between paper, may 

 be preserved separately on a shelf.
