The check lists referred to by check-list numbers are indicated by 
the first letter of the order represented placed immediately above the 
number. 
The spaces on the note sheets are numbered by a consecutive number- 
ing machine, and may continue from one to as high a number as desired. 
During collecting tours and other outdoor investigations, one of these 
pads, held in a case provided for the purpose, is carried in the pocket 
the same as an ordinary note-book. Entries are made in the numbered 
spaces at the time specimens are collected, and a corresponding number 
is placed with and remains with every specimen or set of specimens, 
experiment, etc., referred to. When entries have been made in all of 
the numbered spaces, the pad is taken from the case, the edges trimmed^ 
and all surplus attachments removed. Then it is placed in the acces- 
sions catalogue file, and, as other pads are subsequently filled, they are 
filed with the first in consecutive order; thus forming from the first, 
and at any time after, a complete catalogue of all accessions. 
THE SPECIES CATALOGUE. 
This contains a complete list of the names of all the determined 
species in the collections, together with references to all notes, records, 
experiments, and investigations, and all other available information 
relating to each. The names, check-list numbers, accessions catalogue 
numbers, and other references are entered on cards or slips of uniform 
size (6§ by 4£ inches), and the cards are arranged in systematic order 
according to the standard check list and synopsis of the order repre- 
sented, and are filed in cases the same as the cards of an ordinary card 
index. 
Two sets of cards are used for this catalogue. One called the species 
cards, and the other the record cards. The species cards have two 
spaces at the top, each five- sixteenths of an inch wide. The first space 
is for the check-list number or generic name. The second space is for the 
generic and specific name only, and the space below is for the synonyms, 
references to descriptions, classifications, corrections, etc. In no case 
should an entry be made on this card unless the species has been 
identified at least generically. If an identified species has a check-list 
number, the number alone will be sufficient to keep the card in its 
proper position in the catalogue file, but in case there is no check-list 
number for the species, the name of the order should be entered at the 
left in the upper space, the genus in the center, and the family at the 
right. This will facilitate keeping the species cards in their relative 
positions. 
The record cards differ from the species cards in having but one 
space at the top. This space is for the check-list number, or if there 
is no check list in the order represented, the full name of the species 
is entered. The space below the line is for accessions, catalogue num-
