2 may be modified for the purpose. In the latter cise the 

 number given to each plant should also appear on the hbel 

 aS in No'. 3. If the collecting- falls within a period of a few 

 weeks, the date may also be printed. Nos. 2 and 3 are the 

 size of the originals and printed from the only styles of type 

 that can be recommended for this work. No. 4 is another 

 special label whose purpose appears from its face. 



Many collectors prefer labels like Nos. i and 2 with 

 only the headlines printed. This is a matter of individual 

 preference, but the tendency seems to be toward the styles 

 here given. Labels should be printed on white or cream- 

 colored paper that is sufficiently sized to take the' ink for the 

 rest of the label without blurring. It is well to avoid thick 

 paper, as it is more difficult to paste smoothly to the sheets. 

 Labels should always be fastened to the lower right-hand 

 corner of the sheet, and for this purpose paste is better than 

 mucilage. Some collectors give their labels a sort of individ- 

 uality by printing some character on it before the regular 

 label is printed. Thus the label with the plants collected in 

 Yucatan by Dr. Millspaugh bears a green Y across which the 

 usual label is printed. If this under-tint is not too strong, 

 such labels are of value in enabling one to distinguish at a 

 glance, when consulting an herbarium, whether the specimen 

 is one for which he is searching or not.
