The piece of shell having been mounted on a Stick, a grip is wanted in which to hold the Stick with the left hand, while work is carried on with the right hand. This may be obtained by using a piece of wood, like that in the illustration (Fig.6), and screwing it to the top of a wooden table, so that the notch is projected a couple of inches in advance of the edge of the table; or, if no special table is available, a Holdfast should be purchased, such as is shown in Fig.6. This is screwed to the edge of a table from below, and fits any kind of table, leaving no mark whatever. The price of a Holdfast varies from 1s. to 2s. 6d., and the article may be purchased at any tool-shop. A simpler form of Holdfast may be obtained by purchasing an iron screw-clip, which may be had from any ironmonger, and getting a notched piece of wood, as shown in the above cut, and this is considered preferable by many as furnishing a steadier grip while work is going on.
