[Ill.u.s.tration]

[Page 131]

For the capture of mice this is both a simple and effective contrivance, and it may be enlarged so as to be of good service for larger animals.

Procure two boards, one foot square and one inch thick, and secure them together by two hinges, as in the ill.u.s.tration. a.s.suming one as the upper board, proceed to bore a gimlet hole three inches from the hinges. This is for the reception of the bait stick, and should be cut away on the inside, as seen in the section (_a_), thus allowing a free play for the stick. Directly beneath this aperture, and in the lower board, a large auger hole should be made.

A stout bit of iron wire, ten inches in length, is now required.

This should be inserted perpendicularly in the further end of the lower slab, being bent into a curve which shall slide easily through a gimlet hole in the edge of the upper board. This portion is very important, and should be carefully constructed. The bait stick should be not more than three inches in length, supplied with a notch in its upper end, and secured in the aperture in the board by the aid of a pivot and staples, as is clearly shown in our drawing.

The spindle is next in order. It should consist of a light piece of pine eight and a half inches in length, and brought to an edge at each end. A tack should now be driven at the further edge of the upper board on a line with the aperture through which the wire pa.s.ses. Our ill.u.s.tration represents the trap as it appears when set. The upper band is raised to the full limit of the wire. One end of the spindle is now adjusted beneath the head of the tack, and the other in the notch in the bait stick. The wire thus supports the suspended board by sustaining the spindle, which is held in equilibrium. A slight touch on the bait stick soon destroys this equilibrium: a flap ensues, and a dead mouse is the result. The object of the auger hole in the lower board consists in affording a receptacle for the bait when the boards come together, as otherwise it would defeat its object, by offering an obstruction to the fall of the board, and thus allow its little mouse to escape.

It is, therefore, an essential part of the trap, and should be carefully tested before being finally set.

THE BOX PIT-FALL.

We now come to a variety of trap which differs in its construction from any previously described. It secures its victims alive, and without harm, and, when well made, is very successful.

[Page 132]

It may be set for squirrels, chipmunks, rats, mice, and the like, and on a large scale for muskrats and mink.

[Ill.u.s.tration]

The trap is very easily made, and is represented in section in our ill.u.s.tration, showing the height and interior of the box. For ordinary purposes the box should be about twelve or fourteen inches square, with a depth of about eighteen inches. A platform consisting of a piece of tin should then be procured. This should be just large enough to fit nicely to the outline of the interior of the box without catching. On two opposite sides of this piece of tin, and at the middle of each of those sides, a small strip of the same material should be wired, or soldered in the form of a loop, as shown in the separate diagram at (_b_). These loops should be only large enough to admit the end of a shingle-nail. A scratch should now be made across the tin from loop to loop, and on the centre of this scratch another and larger strip of tin should be fastened in a similar manner as shown in our diagram, at (_a_), this being for the balance weight. The [Page 133]

latter may consist of a small stone, piece of lead, or the like, and should be suspended by means of a wire bent around it, and secured in a hole in the tin by a bend or knot in the other extremity.

Further explanations are almost superfluous, as our main ill.u.s.tration fully explains itself.

[Ill.u.s.tration]

After the weight is attached, the platform should be secured in its place, about five inches from the top of the box. To accomplish this and form the hinges, two shingle-nails should be driven through the side of the box into the tin loops prepared for them. To do this nicely requires some considerable accuracy and care, and it should be so done that the platform will swing with perfect freedom and ease, the weight below bringing it to a horizontal poise after a few vibrations. Care should be taken that the weight is not too heavy, as, in such a case, the platform will not be sensitive on its balance, and, consequently, would not work so quickly and surely.

The weight should be _just heavy enough_ to restore the platform to its perfect poise, and no more. This can be easily regulated by experiment. The bait should then be strewn on both sides of the platform, when the trap is set, and the luckless animal, jumping after the bait, feels his footing give way, and suddenly finds himself in the bottom of a dark box, from which it is impossible for him to escape except by gnawing his way out. To prevent this, the interior of the box may be lined with tin.

By _fastening_ the bait--a small lump or piece--on each side of the tin, the trap will continually reset itself, and, in this way, two or three individuals may be taken, one after the other. Muskrats are frequently caught in this trap, it being generally buried in the ground so that its top is on a level with the surface. In this case it is necessary to arrange the platform lower down in the box, and the latter should be of much larger dimensions than the one we have described.

[Page 134]

For ordinary purposes the box should either be set in the ground or placed near some neighboring object which will afford easy access to it. No less than a dozen rats have been caught in a trap of this kind in a single night.

CAGE TRAP.

[Ill.u.s.tration]

The common cage trap is well known to most of our readers, and for the capture of rats and mice, it is one of the most efficacious devices in existence. The construction of one of these traps is quite a difficult operation, and we would hesitate before advising our inventive reader to exercise his patience and ingenuity in the manufacture of an article which can be bought for such a small price, and which, after all, is only a mouse trap. If it were a device for the capture of the _mink_ or _otter_, it might then be well worth the trouble, and would be likely to repay the time and labor expended upon it. We imagine that few would care to exercise their skill over a trap of such complicated structure, while our pages are filled with other simpler and equally effective examples.

For the benefit, however, of such as are of an inventive turn of mind, we subjoin an ill.u.s.tration of the trap to serve as a guide.

The principle upon which it works is very simple. The bait is [Page 135]

strewn inside the cage, and the rats or mice find their only access to it through the hole at the top. The wires here converge at the bottom, and are pointed at the ends. The pa.s.sage downwards is an easy matter, but to _escape_ through the same opening is impossible, as the pointed ends of the wires effectually prevent the ascent.

It is a notable fact, however, that the efforts to escape through this opening are very seldom made. The mode of entering seems to be absolutely forgotten by the captive animals, and they rush frantically about the cage, prying between all the wires in their wild endeavors, never seeming to notice the central opening by which they entered. This is easily explained by the fact that the open grating admits the light from all sides, and the enclosed victims are thus attracted to no one spot in particular, and naturally rush to the extreme edges of the trap, in the hope of finding an exit.

If a thick cloth be placed over the cage, leaving the opening at the top uncovered, the confined creatures are soon attracted by the light, and lose no time in rushing towards it, where their endeavors to ascend are effectually checked by the pointed wires.

Profiting by this experiment, the author once improvised a simple trap on the same principle, which proved very effectual. We will call it

THE JAR TRAP.

In place of the wire cage, a gla.s.s preserve-jar was subst.i.tuted.

A few bits of cheese were then dropped inside, and the top of a funnel inserted into the opening above. This completed the trap, and it was set on the floor near the flour barrel. On the following morning the jar was occupied by a little mouse, and each successive night for a week added one to the list of victims. A stiff piece of tin, bent into the required shape, may be subst.i.tuted for the funnel top, or even a very heavy piece of pasteboard might answer.

BOWL TRAPS.

Very effective extempore traps may be set up in a few minutes by the use of a few bowls. There are two methods commonly employed.

One consists of the bowl and a knife-blade. An ordinary tableknife is used and a piece of cheese is firmly forced on to the end of the blade, the bowl is then balanced on the edge, allowing the bait to project about an inch and a half beneath the bowl. The odor of cheese will attract a mouse almost anywhere, and he soon finds [Page 136]

his way to the tempting morsel in this case. A very slight nibble is sufficient to tilt the blade and the bowl falls over its prisoner.

In the second method a thimble is used in place of the knife. The cheese is forced into its interior, and the open end of the thimble inserted far beneath the bowl, allowing about half its length to project outward.

The mouse is thus obliged to pa.s.s under the bowl in order to reach the bait, and in his efforts to grasp the morsel, the thimble is dislodged and the captive secured beneath the vessel. Where a small thimble is used, it becomes necessary to place a bit of pasteboard or flat chip beneath it, in order to raise it sufficiently to afford an easy pa.s.sage for the mouse. Both of these devices are said to work excellently.

FLY PAPER.

A sheet of common paper, smeared with a mixture composed of mola.s.ses one part, and bird-lime six parts (see page 97), will be found to attract large numbers of flies and hold them prisoners upon its surface.

Spruce gum, warmed on the fire, and mixed with a little linseed oil, is also excellent. For a genuine fly trap, the following stands unrivalled.

FLY TRAP.

Take a tumbler, and half-fill it with strong soap suds. Cut a circle of stiff paper which will exactly fit into the top of the gla.s.s.

In the centre of the paper cut a hole half an inch in diameter, or, better still, a slice of bread may be placed on the gla.s.s.

Smear one side of the disc with mola.s.ses, and insert it in the tumbler with this side downward. Swarms of flies soon surround it, and one by one find their way downward through the hole. Once below the paper, and their doom is sealed. For a short time the mola.s.ses absorbs their attention, and they, in turn, absorb the mola.s.ses.

In their efforts to escape, they one by one precipitate themselves in the soap suds below, where they speedily perish. The tumbler is soon half-filled with the dead insects, and where a number of the traps are set in a single room, the apartment is soon ridden of the pests.

STEEL TRAPS AND THE ART OF TRAPPING.

[Ill.u.s.tration: P]a.s.sing from our full and extended ill.u.s.trated list of extempore, or "rough and ready" examples of the trap kind, we will now turn our attention to the consideration of that well-known implement, the trade _steel_ trap. Although the foregoing varieties often serve to good purpose, the Steel Trap is the princ.i.p.al device used by professional trappers, and possesses great advantages over all other traps. It is portable, sets easily and quickly, either on land or beneath the water; can be concealed with ease; secures its victims without injury to their fur, and by the application of the spring or sliding pole (hereafter described) will most effectually prevent the captive from making his escape by self-amputation, besides placing him beyond the reach of destruction by other animals.

The author has known trappers who have plied their vocation largely by the aid of the various hand made traps, described in the earlier pages of this book, and with good success. But in the regular _business_ of systematic trapping, their extensive use is not common. The experience of modern trappers generally, warrants the a.s.sertion that for practical utility, from every point of view, the steel trap stands unrivalled.
