Dar Art: 
Paul rrigton is using the aville Grove censuses for comparison 
with Prairie du Sac, and he has pointed out some discrepancies 
between your censuses in Wildlife History of fville Grove and 
some figres I had sent him. These discrepancies are commented on 
in my letter to him attached. 
oiestion 1. Can you roollect whether the first Hungarian coams 
listed In your Table 5 jo 119 was made at the end of 1934 or possibly 
in the spring of 1934?  I h     alwaysassu   e  it to be a late fall 
census, but I cannot now prove It from the records. 
I find an old report by you and Ziegler udated, which gives a 
census for Janxary 1, 1934 as 300 Runs ? 
Jamaary 1, 1935 as 200   '   T 
January 1, 193b as 220     without a question mark 
Since the 220 is almost identical with the 223 given in your table 
5 for Januar7 1, 1936, am I safe in assuming that the 116 figure 
is a refinement of the 200 figure for Janary 1, 19351 
The atlas shows that the 116 figuxe for 1935 covered only 1200 acres, 
and specifies the farms which were omitted . In my letter to Peal, 
I have suggested an arbitrary correction to pro-rate this figure 
to the full acreage. Could Paul use this with a question mark? 
I know you have poor facilities for writing. If you will just 
scratch your answer on the margins of this and send it t me or to 
Paul, it will suffice.
