The first thought that comes into my mind concerning this subject is borrowing and lending tools. I wish I were able to do this part of the subject full justice, but perhaps space in Carpentry and Building would not be available for me to enlarge upon it. When I began the trade it was expected that every journeyman should furnish his own tools to work with. Nowadays it seems to be that each one expects some one else to furnish him tools. It is said, and I believe it is true, that there is no other trade which has so large a proportion of botches to skilled workmen as that of carpentry. The question arises—why is it so? It seems to me that borrowing tools causes more of it than all other reasons put together. This perhaps is a broad assertion, but arguments can be advanced in proof of it.

A Wrinkle in Sawing
A try-square is not always at hand when it is desired to saw a stick, and when it is handy some mechanics prefer to work by “guess” than otherwise. When a bright, straight saw is placed upon a stick or on the edge of a board, the reflection of the stick or board in the saw
is sufficiently well defined to permit of placing the saw so that the reflected image coincides with the object reflected, forming a continuous straight line. If the sawing is done while the image and the stick are in line, the stick will be cut at right angles.
It is obvious that a line may be drawn at right angles to the stick by arranging the saw as shown in Fig 2. If, after forming this line, the saw be placed across the stick so that the line and its reflected image and the stick and its reflected image form a square, with the
reflected image and the stick lying in the same plane, as shown in Fig. 3, the stick may be sawed at an angle of forty-five degrees, provided the saw is held in the same position relative to the stick.
