We had planned to make a large open fireplace in the cabin, and this necessitated cutting an opening in the rear wall. But we did not want to cut the opening until the wall was built up to its full height lest it might buckle while the remainder of the logs were being placed in position. So we merely cut a piece out of the top log to make room for a saw when we were ready to cut the complete opening. As our fireplace was to be 5 feet in width, a 5-foot piece was cut out of the center of the log. Then the ends were supported by cleats nailed on each side, as shown in Fig. 269. This done the building was continued as before, but as the walls grew we found it more and more difficult to raise the logs to position. We could not lift them directly to the top of the wall, but had to roll them up on “skids”; that is, on a pair of 14-foot logs which were laid against the top of the wall. When the walls had reached a height of about 5 feet above the foundation logs, a length 4 feet 9 inches long was cut out of the top log to allow space for sawing out the front door and window, and also a 30-inch piece was cut out for the side window. Cleats temporarily held the sawed ends of the logs, while the walls were carried on up to a height of a little over 6 feet from the foundation logs.

Then we started laying the roof. A 16-foot log was now notched in place at each side, with its forward end projecting about 3 feet over the front of the cabin to form a shelter in front of the building. A pair of 12-foot logs were then laid in position. The next pair of 16-foot logs were laid about 20 inches in from the sides, and after a pair of the cross logs had been set in place a third pair of logs were laid about 40 inches from the sides. Finally, a single 16-foot log was set in place at the center, to serve as the ridge beam of the roof. The roof logs were all carefully tested to see if they were sound before we laid them in place, because we did not want to run any risk of the roof falling in, particularly in the winter time, when it would be heavily covered with snow. A chalk line was drawn from the ridge beam to the lower roof beam, and the cross logs were sawed off along this line, as indicated in Fig. 271. Several slabs were now procured and laid across the roof beams to serve as rafters. These rafters projected about 18 inches beyond the side walls of the cabin, so as to support the eaves. Over the rafters we laid a roofing of slabs, starting with the bottom and lapping them, as we had done on our tree house.
