AN EXHIBIT OF A SYSTEM OF MAKING PEDIGREE 
RECORDS. 
Exhibited by Dr. Raymond Pearl, 
Biologist of the Maine Agricultural Experiment Station, Orono, 
Maine. 
This exhibit consists of a series of blank record forms designed 
to illustrate the method of keeping pedigree records which has been 
in use at the Maine Agricultural Experiment Station for a period of 
five \ears, in connection with its work in the experimental study of 
inheritance in poultry and in various plants. The advantages which 
have been found by experience to inhere in this system of pedigree 
record keeping are (a) simplicity ; (b) ease or operation ; (c) small 
chance for error in the keeping of large masses of pedigree records ; 
(d) uniformity of the system, such that records of all kinds, in any 
way pertaining to the work, may be brought together with great ease 
for consultation or study. 
In addition to the record blanks there are exhibited also various 
marking devices and other apparatus connected with the proper 
working of the plan. 
It should be noted that while the blanks here exhibited are 
devised particularly for work with poultry and plants, the same 
system, with slight modifications, may be successfully applied to the 
keeping of human pedigree records ; indeed it is a pleasure to state
