and the longest and heaviest logs should be about as large around as a lead-pencil and measure not more than eight

Fig. 394. require notches at each end, but only on the upper side (Fig. 394). When erecting the house fit the cross logs together at the notches (Fig. 395), in order to make the walls
Fig. 395. firm and to avoid wide spaces between the logs. Let the elevation or height of the house be four inches (Fig. 396). In building the roof use end logs graduated in length (Fig. 397). These gabled ends should raise the house two inches through the centre. Before
Fig. 396. adding the roof, slide in two extra side logs, each half an inch or so longer than the side logs proper; place one at each end of the top of the house along the inside of the last logs on top of the side walls (Fig. 398, F E). The longer logs are used to extend the roof back and front beyond the building, causing it to project as do
