Suggestions ot Further Deer Trapping: 
Regarding the WISCONSIN DEER TRAP,*' this trap might profitably 
be modified in the following ways: 
1. The trap should be at least six inches longer. 
2. The treadle should be further forward in the trap. 
3. The trap might well be at least two inches wider, 
although this is not essential where trapaportation 
Is an important factor. 
4. It would be a decided advantage to have the traps 
weathered in and not newly constructed. 
The WISCONSIN DEER TRAP is adapted to temporary use, such as the 
trapping of deer doing damage, etc., but for permanent use, as in the 
annual trapping up of surplus deer on a game refuge, private preserves, 
etc., I am confident that another trap, non-portable, would be more 
satisfactory, used in conjunction with the small box trap. The non- 
portable trpp would consist of an un-roofed board room built in the 
woods in a spot permanently frequented by deer. The enclosure ought 
to be at least twelve feet square and at least twelve feet high with 
one large door, say four feet in width and with one or more openings 
Just large enough to fit the door of the small WISCONSIN DEER TRAP. 
Deer would enter the large board enclosure (preferably this room should 
enclose a permanent salt lick) very readily. It would be open at all 
times of the year. When trapping started, the two small traps would 
be placed in the two small door-ways and the large door would be con- 
nected with a trigger. This would amount to trapping the deer twice. 
It Wld first be trapped in the big board room. Here it could not 
injure itself, and in trying to find a way out, it would enter the 
shipping crate trap. If necessary, the small traps could be set at the 
end of small chutes. This plan Is essentially the plan of the Cleveland 
Cliffs Iron Company of Grand Island, aichigan, but with modifications. 

The Practical Application of Deer Trapping: 
Under the methods developed and suggested, it Is entirely possible 
to trap deer for re-stocking purposes. These methods could be put to 
excellent use, for instance, at the Crandon state game refuge, where 
deer are in some localities probably even too numerous for their own 
welfare. By use of the permanent type of trap, this work could be 
carried on cheaply, and almost any number of deer could be made avail- 
able for restocking work. The time ought to come, and undoubtedly 
must come, when our game refuges and parks shoudl be restocked with deer

and other wild animals. In Pennsylvania live bear are commonly 
trapped for restocking. There is no reason why any native animal or 
bird cannot be trapped at a reasonable cost. It would be a great 
credit to this state to take an active part in restocking by trans- 
plantatioh. It seems to me that this is a progressive way of looking 
at our Wisconsin game problems since undoubtedly transplantation offers 
qchepp, efficient and thoroughly desirkble method of replenishing game. 
his method, of course, should be used in conjunction with other means. 
From a game breeder's viewpoint, there are only rare cases in 
which valuable game birds or animals need be killed because of dakage 
complaints. It is entirely practicable in most cases to trap the 
animals or birds alive. Furthermore, live animals if sold on the 
market can bring from twice to several times the pelt or meat value 
of the animal. In my opinion, this could be applied in many cases 
to deer, bear, beaver, mink, pheasants and most of the other  ame 
which commonly causes damage complaints. From a game breeder s 
viewpoint, live trapping is more efficient and more in line with real 
conservation than the antiquated methods of shooting or pelt trapping.
