The first time any working plans of an underground house for boys were published was when an article by the present writer on the subject appeared in the Ladies' Home Journal. Afterward it was published with a lot of similar material in "The Jack of All Trades." Since then other writers have not hesitated to use the author's sketches with very little alteration; imitation is the sincerest compliment, although it is not always fair, but it does, however, show the popularity of the underground-house idea.
The American boy's hogan may be built like the preceding shacks of the material found in the woods or it may be constructed of old boards and waste material to be found in village back yards or on the farm, or, if the boys have the price or if they can interest their fathers or uncles in their scheme, it may be built of milled lumber procured at the lumber-yard.
Frame
Procure some good, sound planks and some pieces of two by four with which to build your frame. The hogan should be large enough to allow room for a table made of a packing-case, some benches, stools, or chairs, and the ceilings should be high enough for the tallest boy to stand erect without bumping his head.
Furniture
One funny thing about this house is that it must be furnished before it is built, because the doorway and passageway will be too small to admit any furniture larger than a stool. Select or make your furniture and have it ready, then decide upon the location of your hogan, which should be, like the Western dugouts, on the edge of some bank ([Fig. 158]). In this diagram the dotted line shows how the bank originally sloped.
Foundation
The real hard work connected with this is the digging of the foundation; one Y. M. C. A. man started to build one of these hogans, but he "weakened" before he had the foundation dug. He wrote the author a long letter complaining of the hard work; at the same time the author was receiving letters from boys telling how much fun they had in building and finishing their underground houses.
Caves
Ever since "Robinson Crusoe" and "Swiss Family Robinson" were written cave houses have been particularly attractive to boys; no doubt they were just as attractive before these books were written, and that may be the reason the books themselves are so popular; at any rate, when the author was a small boy he was always searching for natural caves, or trying to dig them for himself, and so were all of his companions. One of the most charming features of the "Tom Sawyer" and "Huckleberry Finn" stories is that part connected with the cave.
