Can somebody help me with this: Last summer, Freddy built a log cabin on a stretch of land his grandfather had left him. He wanted to build it all by hand, so first he began felling trees. Then, he followed up with the arduous processes of hacking off the branches and limbs from the trunks. Once Freddy had enough sturdy logs, he and a friend used wedges and sledgehammers to split the logs so they could be used in constructing the façade. Following that, Freddy began assembling the framework of the cabin. He laid the post and beam foundation, put in the floorboards, then constructed the supporting walls. After that, Freddy and friends began slotting logs and caulking joints to construct the exterior wall of the cabin. Once finished, Freddy was able to fasten the windows and doors into the openings where they should go. Finally, he was able to shingle the roof. Although the cabin in the woods is very simple and plain, Freddy is happy he was able to build it all with the help of some friends and good, hard work.
