After dinner the work of building went on apace. The main crib of the house was finished by noon of the next day, and the roof and gables only remained to be completed after that. This was to be done as follows:
Logs to form the gables were cut, each a few feet shorter than the one below. Then poles six inches in diameter were cut to form a resting place for the clapboards, and were placed lengthwise the building, resting in notches in the steadily shortening gable timbers. The gable timbers were permitted, however, to extend two feet or so beyond the notches in which the lengthwise poles rested, and a second notch was cut in each end of each of them. When a row of clapboards was laid on the lengthwise poles, another lengthwise pole was placed on top to hold the clapboards in place, and this top pole rested in the outer notches of the gable logs, thus securely holding the roof in position, and as the clapboards overlapped each other as shingles do, the roof was rainproof.
Meantime Jack had been riving clapboards with a fro. Does the reader know what a fro is? The dictionaries do not tell you in any adequate way, though in Virginia and throughout the south and the great west that implement has played an important part in enabling men to house themselves with clapboards or shingles for their roofs. So I must do the work that the dictionaries neglect. A fro is an iron or steel blade about eight or ten inches long, about three inches wide, a quarter of an inch thick at top, tapering to a very dull edge at bottom. In one end of it is an eye to hold a handle.
The fro is used in splitting out clapboards and rough shingles. The operator places its dull edge on the end of a piece of timber of proper width, at the distance of a clapboard's thickness from the side of the timber. Then he hits the back of the fro blade with a mallet or club, driving it well in like a wedge. Then, by working the handle backwards and forwards, and pushing the fro further and further into the crack, as it opens, he splits off a shingle, or a clapboard, as the case may be. In the south, and in some parts of the west nearly all of the shingles and clapboards used are still split out in this way with the fro. Until recent years, when shingle making machines were introduced, all shingles were made in that way, so that next to the axe, and the pitsaw, which used to do the work now done by the saw mill, the fro played the most conspicuous part in the creation of human habitations in all that pioneer period when sturdy arms were conquering the American wilderness and stout hearts were creating the greatness in which we now rejoice. It is stupid of the dictionaries not to tell of it.
In splitting out his clapboards from three-cornered sections of his chestnut logs, Jack gradually reduced those sections to a width too small for the further making of clapboards. This left in each case a three-cornered stick two inches thick at its thickest part, and perhaps three inches wide to its edge. The Doctor wanted to utilize these sticks for firewood and proposed to carry a lot of them to the temporary shelter for that purpose.
"Not by any means," said Jack. "Those wedge-shaped pieces are to be used for chinking."
"What's chinking?" asked the Doctor.
"Why, you see," answered Jack, "the logs of which our house or hut is built, are not quite straight, though they are the straightest we could find in the woods. There are spaces between them that are open, and when the zero weather comes we should be very uncomfortably cold in there if these spaces remained open. No fire that we could make in our chimney would keep us warm under such conditions. So we must stop up the cracks. We'll do that by fitting these pieces of chinking into the cracks between the logs, and then 'daubing' the smaller cracks with mud. That's an operation that will try your resolution, Doctor, and determine whether you are really only sixteen years old, as we voted that you were, or are a much older person, to be specially considered by us boys—for I don't know any more disagreeable job than daubing a log cabin."
"Good!" answered the Doctor. "I'll submit myself to the test very gladly. You'll show me how to 'daub' of course, and if I don't 'daub' with the best and youngest of you, then I'll give up and go down the mountain, acknowledging myself a failure. But I give you fair warning that I don't expect or intend either to give up or to go down the mountain."
"We should all be very sorry if you did, Doctor. We've adopted you now. We've decreed that for this winter, at any rate, you are only sixteen years of age, and upon my word, if you'll allow me to say so—"
