��Measuring box on a wheelbarrow for ob- taining the proper amounts of concrete

steel body wheelbarrow pan with a trans- verse wood gage of the same shape as the inside of the pan. This gage is moved up and down in the pan, according to the amount of concrete to be carried, the latter being measured between the gage- board and the rear end of the pan. The gage-board may be set at any desired position by means of a transverse bar across the top of the pan. The bar is held in place by two pins inserted through any one of a series of small holes along the sides of the pan at the top. The gage- board is held against the transverse bar by a vertical wooden piece nailed to a web fitted to the gage-board at right angles to it at the open end. When the concrete is to be dumped, the gage-board is re- moved.

��Applying Grease to Working Gloves to Make Them Wear

A FRIEND of mine who does heavy work of various kinds which requires gloves, and heavy leather gloves at that, advises me that gloves can be made to wear almost like iron by applying axle grease sparingly and being very careful not to get it on the cloth stitching, as the axle grease may disintegrate it- somewhat.

Making a Photographic Timer out of an Ordinary Watch

A SIMPLE adaptation of an ordinary watch to use as a timer of value in long photographic exposures by photo- engravers and printers, or for use in timing action of developer, can be made by painting a narrow line on the under side of the edge of the watch crystal. Then, by revolving the crystal till the mark coincides with the minute hand, it is easy to register the exact time that ex- posure began. — George Parke.

Joining the Ends of Carpet Rags Without Sewing

AN old backwoodsman used this . method of joining carpet rags end to end, without sewing the strips together. He mounted a strong knife blade, pre- viously shaped like a crochet needle, as shown in Fig. 1, on the bench he used for a seat. The point and upper edges of the knife were sharpened as shown in Fig. 2. Taking the ends of two strips, he pressed them down over the blade. Fig. 3, until they were as shown in Fig. 4. One end was looped under the eye of the needle, Fig. 5, and while holding the ends A and

B, Fig. 6, they were drawn upward. The resultant knot, Fig. 7, can be shaped as in Fig. 8 and drawn tightly as in Pig. 9. Other pieces are attached in the same manner to make a continuous line for the weaving. — James M. Kane.
