Depr Nr. Leopold; 
Here is the nuail trap roughly sketched for you. I have excli  ded 
The covering to reduce unecessary draweing time. If there are any 
cu-stions concerning its construction I'll he glad to help clear them 
up. 
I'm alao l iving you our Madison Fish f[ttchery trappinr results 
to date for your interest: 
Unbanded birds of the year --- 34 (58/, of the unbanded trapped) 
Unbznded birds over a year --- 25 (42Y of the unbunded trapped) 
Danded a year ao -----------  18 (including these recttches 
Banded two years ago --------- 2 would give 57% old to 34,0 ,,oun.) 
Eepeats from all years -------  32 
111 total catches 
The per cent of old to young nay be based on two interpretationes 
1. Using birds that were trapped this year for the first time, 
2. Using banded and unbanded lbirds trapued this year.  Lhis 
way of figuring would Five a hli'er percentage of old birds 
than young birds in the total population.
