First lay the foundation, eight by fifteen feet, and then you may proceed to dig your post-holes. The outside of the posts should be flush or even with the outside edges of the sills and end beams of the house as shown in the diagram. If there are four posts on each of the long sides they should be equal distances apart.

Dig the holes three feet deep, allowing six inches of the posts to protrude above ground. If you drive two stakes a short distance beyond the foundation in line with your foundation lines and run a string from the top of one stake to the top of the other you can, without much trouble, get it upon a perfect level by testing it and adjusting until the string represents the level for your sill. When this is done, set your posts to correspond to the level of the string, then place your sill on top of the posts and test that with your level. If found to be correct, fill in the dirt around the posts and pack it firmly, then spike your sill to the posts and go through the same operation with opposite sets of posts and sill.

[Ill.u.s.tration: Frame of two-by-fours milled lumber, with names of parts.]

The first difficult work is now done and, with the exception of the roof, the rest only needs ordinary care.

It is supposed that you have already sawed off and prepared about nine two-by-four-inch beams each of which is exactly eight feet long. Set these on edge from sill to sill, equal distances apart, the edges of the end beams being exactly even with the ends of the sills as in Fig. 49. See that the beams all cross the sills at right angles and toe-nail them in place. You may now neatly floor the foundation with one-inch boards; these boards must be laid lengthwise with the building and crosswise with the beams. When this is finished you will have a beautiful platform on which to work, where you will be in no danger of losing your tools, and you may use the floor as a table on which to measure and plan the sides and roof.

Ridge Plank and Rafters

It is a good idea to make your ridge plank and rafters while the floor is clear of rubbish. Lay out and mark on the floor, with a carpenter's soft pencil, a straight line four feet long (_A_, _B_, Fig. 49). At right angles to this draw another line three feet six inches long (_A_, _D_, Fig. 49). Connect these points (_B_, _D_, Fig. 49) with a straight line, then complete the figure _A_, _B_, _C_, _D_ (Fig. 49). Allow two inches at the top for the ridge plank at _B_ and two by four for the end of the side-plate at _D_. You then have a pattern for each rafter with a "plumb edge" at _B_ and a "bird's mouth" at _D_. The plumb edge must be parallel with _B_, _C_ and the two jaws of the "bird's mouth" parallel with _D_, _C_ and _A_, _D_, respectively. Make six rafters of two-by-fours and one ridge plank.

The purlins and collar can be made and fitted after the roof is raised.

Set your roof timber carefully to one side and clear the floor for the studs, ribs, and plates. First prepare the end posts and make them of two-by-fours. Each post is of two pieces. There will be four outside pieces each five feet eight inches in length, which rest on the end beams, and four inside pieces each six feet in length; this allows two inches at the top for the ends of the end plates to rest upon.

Examine the corner posts and you will see that the outside two-by-four rests upon the top side of the end beam and the side-plate rests directly upon said two-by-four. You will also observe that the inside two-by-four rests directly upon the sill, which would make the former four inches longer than the outside piece if it is extended to the side-plate; but you will also notice that there is a notch in the end plate for the outside corner piece to fit in and that the end of the end plate fits on top the inside piece of the corner posts, taking off two inches, which makes the inside piece just six feet long. This is a very simple arrangement, as may be seen by examining the diagram. Besides the corner posts, each of which we have seen is made of two pieces of two-by-fours, there are four studs for the front side, each six feet two inches long. The short studs shown in the diagram on the rear side are unnecessary and are only shown so that they may be put in as convenient attachments for shelves and tool racks.

The first stud on the front is placed two feet from the corner post and the second one about six feet six inches from the first, to allow a s.p.a.ce for a six-foot window; the next two studs form the door-jambs and must be far enough from the corner to allow the door to open and swing out of the way. If you make your door two and one half feet wide--a good size--you may set your last stud two feet from the corner post and leave a s.p.a.ce of two feet six inches for the doorway. Now mark off on the floor the places where the studs will come, and cut out the flooring at these points to allow the ends of the studs to enter and rest on the sill. Next make four ribs--one long one to go beneath the window, one short one to fit between the corner post and the door stud not shown in diagram, another to fit between the door stud and window stud, and another to fit between the window stud and the first corner post (the nearest corner in the diagram).

Next make your side-plate exactly fifteen feet long. Fit the frame together on the floor and nail the pieces together, toe-nailing the ribs in place. Get some help and raise the whole side frame and slip the ends of the studs into their respective slots. Make the end posts plumb and hold them in place temporarily by a board, one end of which is nailed to the top end of the post and the other to the end beam. Such a diagonal board at each end will hold the side in place until the opposite side is raised and similarly supported.

It is now a simple thing to slip the end plates in place under the side-plates until their outside edges are even with the outside of the corner posts. A long wire nail driven through the top-plates and end plates down into the posts at each corner will hold them securely.

Toe-nail a rib between the two nearest end posts and make two window studs and three ribs for the opposite end. The framing now only needs the roof timbers to complete the skeleton of your shop. Across from side-plate to side-plate lay some loose boards for a platform, and standing on these boards let your a.s.sistant lift one end of the ridge plank while with one nail to each rafter you fasten the two end rafters onto the ridge plank, fit the jaws of the "bird's mouth" over the ends of the side-plates, and hold them temporarily in place with a "stay lath"--that is, a piece of board temporarily nailed to rafter and end plate. The other end of the ridge is now resting on the platform at the other end of the house and this may be lifted up, for the single nails will allow movement.

The rafters are nailed in place with one nail each and a stay lath fastened on to hold them in place. Test the ends with your plumb-level and when they are found to be correct nail all the rafters securely in place and stiffen the centre pair with a piece called a "collar." Add four purlins set at right angles to the rafters and take off your hat and give three cheers and do not forget to nail a green bough to your roof tree in accordance with the ancient and time-honored custom.

The sides of the house may be covered with tent-cloth, oilcloth, tin, tar paper, or the cheapest sort of lumber, and the house may be roofed with the same material; but if you can secure good lumber, use thirteen by seven eighths by nine and one quarter inch, tongue-and-grooved, one side planed so that it may be painted; you can make two sideboards out of each piece six feet six inches in length. Nail the sides on, running the boards vertically, leaving openings for windows and doors at the proper places.

If you have made a triangular edge to your ridge board, it will add to the finish and the roof may be neatly and tightly laid with the upper edge of one side protruding a couple of inches over the opposite side and thus protecting the joint from rain. Additional security is gained by nailing what are called picket strips (seven eighths by one and three quarter inches) over each place where the planks join, or the roof may be covered with sheathing boards and shingles. It is not necessary here to give the many details such as the manufacture of the door and the arrangements of the windows, as these small problems can be easily solved by examining doors and windows of similar structures.

A SOD HOUSE FOR THE LAWN

THE difference between this sod house and the ones used in the arid regions consists in the fact that the sod will be growing on the sod house, which is intended for and is an ornamental building for the lawn.

Possibly one might say that the sod house is an effete product of civilization where utility is sacrificed to display; but it is pretty, and beauty is always worth while; besides which the same plans may be used in building

A Real Adobe

and practically are used in some of the desert ranches along the Colorado River. The princ.i.p.al difference in construction between the one shown in Figs. 50, 53, and 57 and the one in Fig. 55 is that in the sod house the sod is held in place by chicken-coop wire, while in the ranch-house (Fig.

55) the dirt or adobe is held in place by a number of sticks.

Fig. 50. Fig. 51. Fig. 52. Fig. 53. Fig. 54. Fig. 55. Fig. 56.

[Ill.u.s.tration: A house of green growing sod and the Colorado River adobe.]

Fig. 50 shows how the double walls are made with a s.p.a.ce of at least a foot between them; these walls are covered with wire netting or chicken-coop wire, as shown in Fig. 53, and the s.p.a.ce between the walls filled in with mud or dirt of any kind. The framework may be made of milled lumber, as in Fig. 50, or it may be made of saplings cut on the river bank and squared at their ends, as shown by detailed drawings between Figs. 50 and 52. The roof may be made flat, like Figs. 54 and 56, and covered with poles, as in Fig. 54, in which case the sod will have to be held in place by pegging other poles along the eaves as shown in the left-hand corner of Fig. 54. This will keep the sod from sliding off the roof. Or you may build a roof after the manner ill.u.s.trated by Fig. 49 and Fig. 51, that is, if you want to make a neat, workmanlike house; but any of the ways shown by Fig. 52 will answer for the framework of the roof.

The steep roof, however, must necessarily be either shingled or thatched or the sod held in place by a covering of wire netting. If you are building this for your lawn, set green, growing sod up edgewise against the wire netting, after the latter has been tacked to your frame, so arranging the sod that the green gra.s.s will face the outside. If you wish to plaster the inside of your house with cement or concrete, fill in behind with mud, plaster the mud against the sod and put gravel and stones against the mud so that it will be next to the wire netting on the inside of the house over which you plaster the concrete. If you make the roof shown in Fig. 54, cover it first with hay and then dirt and sod and hold the sod down with wire netting neatly tacked over it, or cover it with gravel held in place by wire netting and spread concrete over the top as one does on a cellar floor. If the walls are kept sprinkled by the help of the garden hose, the gra.s.s will keep as green as that on your lawn, and if you have a dirt roof you may allow purple asters and goldenrod to grow upon it (Fig. 62) or plant it with garden flowers.

Thatch

If you are going to make a thatched roof, soak your thatch in water and straighten the bent straws; build the roof steep like the one shown in Fig. 57 and make a wooden needle a foot long and pointed at both ends as shown in Fig. 59; tie your thatching twine to the middle of the needle, then take your rye or wheat straw, hay, or bulrushes, gather it into bundles four inches thick and one foot wide, like those shown in Fig. 60, and lay them along next to the eaves of your house as in Fig. 58. Sew them in place by running the needle up through the wire netting to the man on the outside who in turn pushes it back to the man on the inside. Make a knot at each wisp of the thatch until one layer is finished, let the lower ends overhang the eaves, then proceed as ill.u.s.trated by Fig. 66 and described under the heading of the bog ken.

If in place of a simple ornament you want to make a real house of it and a pretty one at that, fill up the s.p.a.ce between the walls with mud and plaster it on the outside with cement or concrete and you will have a cheap concrete house. The wire netting will hold the plaster or the concrete and consequently it is not necessary to make the covering of cement as thick as in ordinary buildings, for after the mud is dried upon the inside it will, with its crust of cement or plaster, be practically as good as a solid concrete wall.

HOW TO BUILD ELEVATED SHACKS, SHANTIES, AND SHELTERS

FOR many reasons it is sometimes necessary or advisable to have one's camp on stilts, so to speak. Especially is this true in the more tropical countries where noxious serpents and insects abound. A simple form of stilted shack is shown by Fig. 63. To build this shack we must first erect an elevated platform (Fig. 64). This is made by setting four forked sticks of equal height in the ground and any height from the ground to suit the ideas of the camp builder. If, for some reason, the uprights are "wabbly"

the frame may be stiffened by lashing diagonal cross sticks to the frame.

After you have erected the four uprights, lay two poles through the crotches, as in Fig. 64, and make a platform by placing other poles across these, after which a shelter may be made in the form of an open Adirondack camp or any of the forms previously described. Fig. 65 shows the framework for the open camp of Adirondack style with the uprights lashed to the side bars; if you have nails, of course, you can nail these together, but these plans are made on the a.s.sumption that you have no nails for that purpose, which will probably be true if you have been long in the woods.

THE BOG KEN

KEN is a name now almost obsolete but the bog ken is a house built on stilts where the ground is marshy, damp, and unfit to sleep upon. As you will see by the diagram (Fig. 66), the house is built upon a platform similar to the one last described; in this instance, however, the shelter itself is formed by a series of arches similar to the Iroquois (Fig. 41).

The uprights on the two sides have their ends bent over and lashed together, forming arches for the roof. Over the arches are lashed horizontal poles the same as those described in the construction of the Iroquois lodge. Fig. 67 shows one way to prevent "varmints" of any kind from scaling the supporting poles and creeping into your camp.

The protection consists of a tin pan with a hole in the bottom slid over the supporting poles. Fig. 66 shows how to lash the thatching on to the poles and Fig. 68 shows how to spring the sticks in place for a railing around your front porch or balcony.

The floor to this bog ken is a little more elaborate than that of the last described camp because the poles have all been halved before laying them for the floor. These are supposed to be afterwards covered with browse, hay, or rushes and the roof shingled with bark or thatched.
