FILING SYSTEM. 
A very convenient method of filing the cost-account and per- 
sonal reports is to inclose all the reports for one month in a manila 
envelope of proper size, on the back of which may be printed a blank 
summary form for the display of the significant figures of all the 
inclosed reports. The envelopes for the various months and camps 
may then be filed in order in a shnple drawer letter file. 
Numbering of Forms. 
Instead of designating the various forms by their names, which 
may be rather cumbersome, it is a good plan to give each of the re- 
ports a form number. The sample forms shown are numbered 
according to a decimal system, by which the numbers serve to desig- 
nate not only the individual forms but also the class of forms to 
which they belong. For example, the forms shown are divided 
into four classes according to their use, as follows: 
Class I. Operating forms, including (1) Requisition; (2) Purchase- 
order; (3) Voucher for supplies and services furnished; (4) Inventory 
of property. 
Class II. Maintenance reports, including (1) Food-item report; (2) 
Summary of quantities and cost of food issued; (3) Report of services 
and supplies other than food. 
Class III. Work reports, including (1) Daily report of construction; 
(2) Monthly report of construction. 
Class IV. Personal reports, including (1) Prisoners' time sheet; 
(2) Movement of prisoners; (3) Daily report of sickness. 
All forms of Class I have in their numbers the figure 1 on the left 
of the decimal point, and the four forms in the class are numbered 
from 1 to 4, respectively, on the right of the decimal point in the order 
in which they are enumerated above. The three forms of Class II 
are designated by the figure 2 on the left of the decimal point, and 
the figures 1 to 3 in the order of enumeration above, on the right of 
the point; and the numbers of forms in Class III and Class IV are 
determined in like manner.
