Boy Scouts Handbook Part 21

{58}

The first attempt I made was with two sticks and a bucket of water. I arranged the bucket in the daytime, so that it could be filled from rim to rim; that is, it was level, and that gave me the horizon line; next, I fastened my two sticks together at an adjustable angle. Then, laying one stick across the bucket as a base, I raised the other till the two sight notches on its upper edge were in straight line for the Pole-star. The sticks were now fastened at this angle and put away till the morning. On a smooth board--the board is allowable because it can be found either far on the plains when you have your wagon, or on the ship at sea--I mapped out, first a right angle, by the old plan of measuring off a triangle, whose sides were six, eight, and ten inches, and applied the star angle to this. By a process of equal subdivision I got 45 degrees, 22-1/2 degrees, finally 40 degrees, which seemed to be the lat.i.tude of my camp; subsequent looking-up showed it to be 41 degrees 10 minutes.

Of course, it is hard to imagine that the boys will ever be so placed that it is important for them to take their lat.i.tude with home-made implements; but it is also hard to imagine circ.u.mstances under which it would be necessary to know that the sun is 92,000,000 miles away.

It is very sure, however, that a boy who has once done this has a larger idea of the world and its geography, and it is likely to help him in realizing that there is some meaning to the lines and figures on the border of his school maps, and that they are not put there merely to add to his perplexities.

To make a scout's sundial, prepare a smooth board about fifteen inches across, with a circle divided into twenty-four equal parts, and a temporarily hinged pointer, whose upper edge is in the middle of the dial. Place on some dead level, solid post or stump in the open. At night fix the dial so that the twelve o'clock line points exactly to north, as determined by the Polestar. Then, using two temporary sighting sticks of exactly the same height (so as to permit sighting clear above the edge of the board) set the pointer exactly pointing to the Pole-star; that is, the same angle as the lat.i.tude of the place, and fix it there immovably. Then remove the two sighting sticks. As a timepiece, this dial will be found roughly correct for that lat.i.tude.

The angle of the pointer, or style, must be changed for each lat.i.tude.

Building a Log Cabin (From Country Life in America. May, 1905 )

There are as many different kinds of log cabins as of any other architecture. It is best to begin with the simplest. The tools needed are a sharp ax, a crosscut saw, an inch auger, and a spade. It is possible to get along with nothing but an ax (many settlers had no other tool), but the spade, saw, and auger save much work.

For the site select a high, dry place, in or near the woods, and close to the drinking-water. It should be a sunny place, and with a view, preferably one facing south or east. Clear off and level the ground.

Then bring your logs. These are more picturesque with the bark left on, but last longer peeled. Eight feet by twelve feet outside makes a good cabin for three or four boys.

Cut and carry about twelve logs, each ten feet long; and twelve more, each fourteen feet long. The logs should be at least six inches through. Soft wood is preferable, as it is easier to handle; the four ground logs or sills, at least, should be of cedar, chestnut, or other wood that does not rot. Lay two of the fourteen-foot logs on the ground, at the places for the long sides, and seven feet apart. Then across them, at the end, lay two short ones, eleven feet apart. This leaves about a foot projecting from each log. Roll the last two into their resting places, and flatten them till they sit firmly. It is of prime importance that each log rest immovably on the one below. Now cut the upper part of each end log, to an edge over each corner. (Fig.

1.)

[Ill.u.s.tration: Log cabin, figures 1 to 10.]

Next put on two long logs, roll them onto the middle, taking care to change off, so the big end at a given comer may be followed next time by the small end and insure the corner rising evenly. Roll one of these large logs close to where it is to be placed, then cut on its upper surface at each end a notch corresponding with the ridge on the log it is to ride on. When ready, half a roll drops it into place. The log should be one to three inches above the one under it, and should not touch except at {61} the ends. Repeat the process now with the other sides, then the two ends, etc., always keeping the line of the corner plumb. As the walls rise, it will be found necessary to skid the larger logs; that is, roll them up on two long logs, or skids, leaning against the wall. (Fig. 2.)

When the logs are in place to the height of four and a half feet from the ground, it is time to decide where the door and window are to be; and at that place, while the next long log is lying on top, bottom up, cut out a piece four feet long and four inches deep. Roll this log into place. (Fig. 3.) One more log above this, or certainly two, will make your shanty high enough for boys. Put on final end logs, then two others across the shanty. (Fig. 4.) Roll up the biggest, strongest log of all for the ridge (sometimes two are used side by side); it should lie along the middle of the four cross pieces shown in Fig. 4.

The two cross logs, B and C, and the ridge log should be very strong, as the roof is heavy. Now we are ready to cut the doorway and window.

First, drive in blocks of wood between each of the logs, all the way down from A to the ground, and from B down to D, and C to E. (Fig. 5.) Saw down now from A half-way through the ground log F. Then from B down to half-way through the log D; now continue from G, cutting down to half through the ground log. Use the ax to split out the upper half of the ground log, between the saw-cuts and also the upper half of the log D.

Hew a flat piece of soft wood, five or six inches wide, about two inches thick, and as long as the height of this doorway. Set it up against the ends of the logs A to F. Bore an auger hole through it into the end of each log (these holes must not be in line lest they split the jamb), including the top and bottom ones, and drive into each a pin of oak. This holds all safely. Do the same on the other side, H to E, and put a small one down B, D, which is the side of the window.

Now we are ready to finish the roof. Use the ax to bevel off the corners of the four cross-logs, A and B. (Fig. 6.) Then get a lot of strong poles, about five feet long, and lay them close together along the two sides of the roof till it is covered with poles; putting a very heavy one, or small log, on the outer edge of each, and fastening it down with a pin into the ridge log. Cut two long poles and lay one on each of the lower ends of the roof poles, as at A, B, and C (Fig.

7), pinning them to the side logs.

Cover this roof with a foot of hay or straw or gra.s.s, and cover {62} that again evenly with about four inches of stiff clay. Pack this down. It will soon squeeze all that foot of straw down to little more than one inch, and will make a warm and water-tight roof. As the clay is very heavy, it is wise, before going inside, to test the roof by jumping on it. If it gives too much, it will be well to add a centre prop.

Now for the door: Hew out planks; two should be enough. Fasten these together with two cross-pieces and one angle-piece, using oak pegs instead of nails, if you wish to be truly primitive. For these the holes should be bored part way with a gimlet, and a peg used larger than the hole. The lower end of the back plank is left projecting in a point. (Fig. 8.) This point fits into a hole pecked with a point or bored with an auger into the door-sill.

Bore another hole near the top of the door (A), and a corresponding one through the door-jamb between two logs. Set the door in place. A strip of rawhide leather, a limber willow branch, or a strip of hickory put through the auger hole of the door and wedged into the hole in the jamb, makes a truly wild-wood hinge. A peg in the front jamb prevents the door going too far out, and a string and peg inside answer for a latch.

The window opening may be closed with a gla.s.s sash, with a piece of muslin, or with the rawhide of an animal, sc.r.a.ped clear of hair and stretched on a frame.

It now remains to c.h.i.n.k and plaster the place.

c.h.i.n.king is best done from the inside. Long triangular strips and blocks of wood are driven in between the logs and fastened there with oak pins driven into the lower log till nothing but small crannies remain. Some cabins are finished with moss plugged into all the crannies, but mud worked into plaster does better.

It should be put on the outside first, and afterward finished form the inside. It is best done really with two plasterers working together, one inside and one out.

This completes the shanty, but a bunk and fireplace are usually added.

The fireplace may be in one corner, or in the middle of the end. It is easiest to make in the former.

Across the corner, peg three angle braces, each about three feet long.

These are to prevent the chimney falling forward.

Now begin to build with stone, using mud as mortar, a fireplace this shape. (Fig. 9.) Make the opening about eighteen inches across; carry it up two feet high, drawing it in a little, then lay a long stone across the front, after which build up {63} the flue behind the corner braces right up to the roof. The top corner-piece carries the rafter that may be cut off to let the flue out. Build the chimney up outside as high as the highest part of the ridge.

But the ideal fireplace is made with the chimney on the outside of the cabin, at the middle of the end farthest from the door. For this you must cut a hole in the end log, like a big, low window, pegging a jamb on the ends as before.

With stones and mud you now build a fireplace inside the shanty, with the big chimney carried up outside, always taking care that there are several inches of mud or stone between the fire and any of the logs.

In country where stone cannot be found, the fireplace is often built of mud, sustained by an outside cribbing of logs.

If the flue is fair size, that is, say one quarter the size of the fireplace opening, it will be sure to draw.

The bunk should be made before the c.h.i.n.ks are plastered, as the hammering is apt to loosen the mud.

Cut eight or ten poles a foot longer than you need the bunk; cut the end of each into a flat board and drive these between the long logs at the right height and place for the bunk, supporting the other end on a crosspiece from a post to the wall. Put a very big pole on the outer side, and all is ready for the bed; most woodsmen make this of small fir boughs.

There are two other well-known ways of cornering the logs--one is simply flattening the logs where they touch. This, as well as the first one, is known in the backwoods of Canada as hog-pen finish. The really skilful woodsmen of the North always dovetail the comers and saw them flush: (Fig. 10)

Sometimes it is desirable to make a higher gable than that which one ridge log can make. Then it is made thus: (Fig. 11.) This is as much slope as a clay roof should have; with any more, the clay would wash off.

This is the simplest way to build a log-cabin, but it ill.u.s.trates all the main principles of log building. Shingle roofs and gables, broad piazzas outside, and modern fitting inside, are often added nowadays in summer camps, but it must be clear that the more towny you make the cabin, the less woodsy it is, and less likely to be the complete rest and change that is desired.

Measuring Distances (See "Two Little Savages," 1903.)

The height of a tree is easily measured when on a level, open place, by measuring the length of its shadow, then comparing that with your own shadow, or that of a ten-foot pole.
