The door shows the two strings _H_ and _K_ coming through gimlet holes near the top. Fig. 218 represents the outside of the door. The strings may be concealed by covering their ends with a board as shown in this diagram, but even if they are not concealed, one unacquainted with the lock will not know how to work them in order to open the door.
_A_ in Figs. 219, 220, and 221 is the latch which is made of a piece of wood about eight or nine inches long by about one and one half inches wide by an inch or three quarters of an inch thick. A hole is drilled near the centre of the latch and a screw placed through which is screwed into the door so that the latch will extend about two or three inches beyond the end of the door.
_D_ (Figs. 219, 220, and 221) is a catch or stop which is fastened to the door-jamb and keeps the end of the latch from flying too far up to lock the door.
_B_ (Fig. 219) is the key which is made of the same sort of wood as the latch; a hole is drilled in this also but it is here placed about one inch from the top. A screw is run through this, as in the hole in the latch, and screwed into the door (Fig. 219).
Fig. _C_, 219 is a small block of wood on which a steel-band spring has been screwed to keep the key in its proper place. The block is screwed to the door a short distance above the top of the key.
Fig. _J_, 219 is a nail or peg placed in the door close beside the key when the key is vertical; this is intended to prevent the key from being shoved over too far by the force of the band spring _F_.
Fig. 219 _L_ is a steel wire spring (a window-shade spring will answer the purpose), fastened to the door at one end and to the latch at the other end, and serves to keep the latch down and in place when locked.
Fig. 219 _K_ is the latch-string, one end of which is fastened to one end of the latch and the other end run through a hole near the top of the door and extending outside the same as the latch-string (Fig. 218).
Fig. 219 shows the positions of the latch and key when the latch is locked; to open the lock from the outside it is necessary to pull the key string first (_H_, Fig. 220), which releases the key; then pull the latch-string, thus lifting the latch while still holding the key string.
The key string is now let go; the spring forcing the key into the position shown in Fig. 221 will keep the door unlocked.
When leaving the room, all that is necessary is to pull the key string which lifts the key, then let go the latch-string, and the latch will spring back to its locked position and the key will also fly back into its position as in Fig. 219. Any one not knowing the combination will be unable to open the door.

[Ill.u.s.tration: Home-made cabin door-locks.]
The Compa.s.s Lock
This lock is made on the same principle as the combination safe lock, but it is a lock any bright boy can make for himself. In the first place, instead of numbers, use compa.s.s divisions; that is, use a disk with the points of the compa.s.s scratched on it and an ordinary door-k.n.o.b with an index mark filed on its base, as shown by Fig. 224 where the finger is pointing.
Hunt up three old door-k.n.o.bs like those shown in Figs. 222, 224, and 225.
When you take one of the door-k.n.o.bs off one end of the shaft you will find several small screw holes in the steel shaft (Fig. 222). Over this end you set a block of hardwood which you fas.h.i.+on out of a square block (Fig. 223) by first cutting off the corners as shown by the dotted lines, then whittling the angles off until it becomes rounded like a compa.s.s face; after which saw off an arc, that is, part of a circle, as shown in Figs.
224, 226, and 227. Next make a square hole through the centre of the circle to fit the square end of the steel shaft of the door-k.n.o.b. The square hole is not the centre of the block as it is now cut, but it is the centre of the block as it was when it was round; that is, the centre of the circle. Insert the square end of the steel shaft into the square hole in the block, and, through a hole carefully drilled for the purpose, put a screw down through the hole in the end of the steel shaft (Fig. 224); this will firmly fix the block on the end of the k.n.o.b. Of course, the k.n.o.b must be inserted through the door before the block is permanently fastened upon the end of the shaft. Fig. 225 shows the edge of the door with the three k.n.o.bs in place. If these k.n.o.bs are so turned (Fig. 226) that their flat edges are parallel with the crack of the door, there is nothing to prevent you from opening the door; but if the k.n.o.bs are so turned (Fig.
227) that the blocks overlap the crack of the door, the door cannot be opened without breaking the lock.
It is evident that we must have some sort of a mark to tell us how to make the proper combination so that the door may be opened. To do this, take the metal washer of the door-k.n.o.b (the upper figure in Fig. 228) or a circular piece or disk of tin and divide it up like a compa.s.s (Fig. 228).
Fasten these disks securely on to the door with nails or screws; place all of the disks with the north point pointing to the top of the door and in line with each other. File in the circular base of each door-k.n.o.b (Fig.
224) a little notch at the black mark where the finger is pointing, then put the door-k.n.o.bs in place and fasten them there (Fig. 225) by s.c.r.e.w.i.n.g the block on their ends (Fig. 224) and securing the screws in the blocks by running them through the shaft. Carefully turn the k.n.o.bs so that the block on the inside fits like those shown in Fig. 226. Jot down in your notebook the position of the index on each k.n.o.b (finger point, 224); one may read northeast, another may read southwest, and another may read south. When one wants to open the door one must turn the k.n.o.bs so that they will read according to the notes and the door may be opened; but unless the indexes read as noted some of them will be turned as in Fig.
227, locking the door, and it may not be opened.
When the door is closed, twist the k.n.o.bs around and it will lock them so that no one else can open the door unless they know the combination. The fact that there _is_ a combination will not be suggested to a stranger by the compa.s.ses, although it might be suggested if there were figures in place of compa.s.s points. But even supposing they did suspect a combination it would take a long time for them to work it out, and no one would do it but a thief. A burglar, however, would not take the time; he would pry open the door with his "jimmy" and, as I have said before, these locks are for the purpose of keeping out tramps, vagrants, and inquisitive boys.
We have no locks yet invented which will keep out a real, professional burglar if he has reason to suppose there are valuables inside.
The safety of your log cabin depends princ.i.p.ally upon the fact that valuables are not kept in such shacks, and real burglars know it.

THE AMERICAN LOG CABIN
NOW that we know how to make doors and door-latches, locks, bolts, and bars, we may busy ourselves with building an American log cabin. It is all well enough to build our shacks and shanties and camps of logs with the bark on them, but, when one wishes to build a log cabin, one wants a house that will last. Abraham Lincoln's log cabin is still in existence, but it was built of logs with no bark on them. There is a two-story log house still standing in Dayton, O.; it is said to have been built before the town was there; but there is no bark on the logs. Bark holds moisture and moisture creates decay by inviting fibrous and threadlike cousins of the toadstool to grow on the damp wood and work their way into its substance.
The bark also shelters all sorts of boring insects and the boring insects make holes through the logs which admit the rain and in the end cause decay, so that the first thing to remember is to peel the logs of which you propose to build the cabin. There is now, or was lately, a log cabin on Hempstead Plains, L. I., near the road leading from Mineola to Manha.s.sett; it is supposed to have been built when the first white settlers began to arrive on Long Island, but this was what was known as a "blockhouse," a small fort. In 1906 Mr. I. P. Sapington said: "I think that I am the only man now living who helped build General Grant's log cabin." Grant's house was what is popularly known in the South as a "saddle-bag" log house, or, as the old Southwestern settlers called it, a "two-pen," the pens being two enclosures with a wide pa.s.sageway or gallery between them, one roof extending over both pens and the gallery.
General Grant was not afraid of work, and, like a good scout, was always willing to help a neighbor. He had a team of big horses, a gray and a bay, and the loads of cord-wood he hauled to St. Louis were so big that they are still talked of by the old settlers. In the summer of 1854 Grant started his log cabin, and all his neighbors turned in to help him build his house.
American Log House
The American log house differs from the Canadian log house princ.i.p.ally in the shape of the roof. Our old settlers made steep gambrel roofs to shed the rain.
"Gambrel! Gambrel? Let me beg You'll look at a horse's hinder leg; First great angle above the hoof, That's the gambrel, hence the gambrel roof."
The Canadians put very flat roofs on their log cabins, usually composed of logs laid over the rafters, making them strong enough to support the heavy weight of snow. The American log cabins, as a rule, are built in a milder climate, and the flat sod roof is peculiar to our Northern boundary and the hot, arid parts of our country. We build the chimneys outside of our log cabins because, as the old settlers would say, "thar's more room out thar" (see Figs. 271, 273).
One-Pen Cabin
Fig. 229 is a one-pen cabin. To build it we first snake our logs to a skid near the site of our proposed cabin (Fig. 167), from which we can roll our logs to our house as we need them. Lay out the corners and square them (Fig. 180); notch the logs with a rounded or U-shaped notch (Fig. 165).
Remember that all the logs should be two or three feet longer than the walls of the proposed building, but the notches must be the same distance apart in order to make even walls. The protruding ends of the logs may be allowed to stick out as they happen to come, no matter how irregular they may be, until the cabin is erected; then with a two-handed saw and a boy at each end they can be trimmed off evenly, thus giving a neat finish to the house.

[Ill.u.s.tration: Hints and suggestions in cabin construction.]
Sills
The largest, straightest, and best logs should be saved for sills or foundations. If you are building a "mudsill," that is, a building upon the ground itself, the sill logs will be subject to dampness which will cause them to rot unless they are protected by some wood preservative.
Wood Preservative
If the logs are painted with two or three coats of creosote before they are laid upon the ground, it will protect them for an indefinite time and prevent decay. Hugh P. Baker, dean of the New York State College of Forestry, writes me that--
two or three applications of warm oil with a brush will be very helpful and will probably be all that the ordinary man can do. Creosote is the best preservative because of its penetrating power and the way it acts upon the fibres of wood, and in the end is cheaper than a good many other things which have been used to preserve timber. In fact, various forms of creosote are best-known preservers of organic matter. There is no advantage in using charcoal at all and I presume suggestions have been made for using it because we know that charred wood is more durable.
Linseed-oil is good; ordinary white-lead paint will be better, but neither of them is as effective as creosote, and both are more expensive. You will find that carbolineum and other patent preparations are recommended very highly; they are good but expensive and the difference in price between these patent preparations and ordinary creosote is much larger than is justified by their increased value. Creosote can be procured in large or small quant.i.ties from a number of concerns. I think we have been getting it for about ten dollars per barrel of fifty or fifty-three gallons.
Creosote
may be purchased in large or small quant.i.ties from various manufacturing companies, such as the Barret Manufacturing Company, 17 Battery Place, New York City, and the Chattfield Manufacturing Company, Carthage, O., handle it in large quant.i.ties.
