It is of great importance that the sheet of ]ja]H;r with in 

 which the plant isjirst placed should not be interfered 

 with during the drying process. The directions as to 

 frequent changes refer only to the sheets not iuimediiitely 

 in contact with the plant. The.se, to ensure the best re- 

 sults, should be changed once a day for the first few 

 days ; less frequently thereafter. Gray recommends 

 ironing with hot irons in order to remove more riii)idly 

 the moisture from fleshy leaves, and in any case to warm 

 the driers in the sun before putting them between the 

 plants. 



Mounting. 



When the specimens are thoroughly drj', the next thing is to 

 mount them, and for this purpose you will require sheets 

 of sti'ong white paper ; a good quality of unruled fools- 

 cap or cheap drawing paper will be suitable. The most 

 convenient way of attaching the specimen to the paper 

 is to take a sheet of the same size as your paper, la}' tlie 

 specimen carefully in the centre, wrong side up, and gum 

 it thoroughly with a ver\' soft brush. Then take the 

 paper to which the plant is to be attached, and lay it 

 carefully on the specimen. You can then lift paper and 

 specimen together, and, by pressing lightly with a soft 

 cloth, ensure complete adhesion. To render plants with 

 stout stems additionally secure, make a slit with a pen- 

 knife through the paper immediately underneath the 

 stem, then pass a narrow band of paper round the stem, 

 and thrust both ends of the band through the slit. The 

 ends may then be gummed to the back of the sheet. 



Sorting and Ticketing. 



The specimen having been duly mounted, its botanical name 

 should be A\Titten neatlj- in the lower right-hand corner, 

 together with the date of its collection and the locality 

 where found. Of course only one Species should be 

 mounted on each sheet ; and when a sufficient number 

 have been prepared, the Species of the same Genus should 

 be placed in a sheet of larger and coarser paper than that 

 on which the specimens are mounted, and the name of 

 the Genus should be written outside on the lower comer. 

 Then the Genera of the same Order should be collected in 

 the same manner, and the name of the Order written 

 outside as before. The Oi-.Ums may thou Iw arranged in 

 accordance with the classification you may be using, and 

 carefully laid away in a dry place. If a cabinet, with 

 shelves or drawers, can be specially devoted to storing 

 the plants, so much the better.
