APPENDIX. 519 



with the season, from two or three days to a week. All delicate speci- 

 mens should be laid in folded sheets of thin and smooth bibulous paper 

 (such as tea-paper), and such sheets, filled with the freshly gathered 

 specimens, are to be placed between the dryers, and so transferred entire, 

 day after day, into new dryers, without being disturbed, until perfectly 

 dry. This preserves all delicate flowers better than the ordinary mode of 

 shifting of the papers which are in immediate contact with the specimens, 

 and also saves much time usually lost in transferring numerous small 

 specimens, one by one, into dry paper, often to the great injury of the deli- 

 cate corolla, &c. 



5. The dried specimens, properly ticketed with the name, locality, &c., 

 and arranged under their respective genera and orders, are preserved in 

 the herbarium, either- in separate double sheets, or with each species at- 

 tached by glue or otherwise to a half-sheet of strong white paper, with the 

 name written on one corner. These are collected in folios, or else lie flat 

 (as is the best mode) in parcels of convenient size, received into compart- 

 ments of a cabinet, with close doors, and kept in a perfectly dry place. 



G. The seeds of plants intended for cultivation, which are to be trans- 

 ported to a distance before being committed to the earth, should first be 

 dried in the sun, wrapped in coarse paper, and preserved in a dr}' state. 

 They should not be packed in close boxes, at least so long as there is dan- 

 ger of the retention of moisture. 



7. Roots, shi-ubs, &c., designed for cultivation, should be taken from the 

 ground at the close of their annual vegetation, or early in the sjirino- before 

 growth recommences, and packed in successive layers of slightly damp (but 

 not wet) Peat-moss (Sphagnum). Succulent plants, however, such as 

 Cacti, may be packed in dry sand. 



8. Plants in a growing state can only be safely transported to a consider- 

 able distance, especially by sea, in the closely glazed cases invented by Mr. 

 Ward ; * where they are provided with the requisite moisture, while they 

 are sufficiently exposed to the light.
