AXE
                "Near the end of March, 1845, I borrowed 
                  an axe and went down to the woods by Walden Pond, nearest to where 
                  I intended to build my house, and began to cut down some tall arrowy 
                  white pines, still in their youth, for timber."
              Hammer 
                and Plasterer's Board
                "My house had in the mean 
                  while been shingled down to the ground on every side in lathing 
                  I was pleased to send each nail home with a single blow of the hammer, 
                  and it was my ambition to transfer the plaster from the board to 
                  the wall neatly and rapidly."
              Plane
                "Before winter I built a 
                  chimney, and shingled the sides of my house, which were already 
                  impervious to rain, with imperfect and sappy shingles made of the 
                  first slice of the log, whose edges I was obliged to straighten 
                  with a plane." 
              Trowel
                "When I came to build my 
                  chimney I studied masonry. My bricks being second-hand ones required 
                  to be cleaned with a trowel, so that I learned more than usual of 
                  the qualities of bricks and trowels."
