out of a box; they climb up quite readily and thouffh seed may 
be broadcast outside they will get into that box. Then the 
peri'orated zinc must be faij-ly coarse or again the l>ox will 
suggest a trap. Finally no matter how roughly made, all 
the parts must work freely. It sounds absurd and yet in 
reality the very roughest work is all that is needed. Aly 
Canary friend said that one night he caught six at one time, 
as he had set the trap a little too heavily. I first practised 
by dropping a pencil-case on to the grid, which, of course, 
must fit pretty accurately or a mouse may get between it 
and the sides or front end of the box and so not upset the 
balance . 
This trap is a grand success, and if it does not succeed 
with you just drop the writer a line with a diagram and no 
doubt youf mistake can be pointed out. If there is a mouse 
and the traj) is near, that mouse is absolutely booked, but 
usually it will only catch one at a time. 
I have found no tendency for birds to get into the 
trap, but even if they did, no harm would come of it, as the 
lid only falls a short distance and would give the Inrd no 
chance of escaping. After giving the trap a good trial, I 
have come to the conclusion the trap is just "IT."

A cock Bengalee and hen Bib Finch paired in June, 
1913, and went to nest the first week in July.

When first examined, it contained four eggs, on the 
10th of July there were five eggs, and on the 2J:th eag shells 
were found outside the box. ^ 
Incubation lasted 13 or 14 days. 
On the 14th of August, the young were seen flying

buff showing on one of them, also a larger patch of white under 
the throat than the others have. 
The remaining three young have a little white showing
