THE O. & O. SEMI-ANNUAL. 47 
with good results a set of comparisons and suggestions to be fol- 
lowed as far as possible by our observers. This list. of compari- 
isons and suggestions, will be forwarded most willingly to all 
who are willing to help by taking observations. Of course, 
notes on subjects not included in these lists are very desirable, but 
if our members will work on these suggestions we hope to get 
something next year ina tangible form from which to deduce 
conclusions. 
To imitate and describe the note of a bird requires great skill, 
a delicate ear and a good memory, and therefore many are apt 
to give it up after a few trials. But any attempt is a great help, 
and as the same difficulty confronts nearly all, the data received 
will be peculiarly fit for comparison, and moreover a little trial 
and experience will greatly improve both the power of discrimi- 
nation and description. 
Therefore, we earnestly hope that all those interested in orni- 
thology will aid in our first attempt at studying bird-songs by 
contributing whatever data may come under their notice.
