The gauge is made of a brass plate, -on the side of which 

 eight notches are cut varying from ^ to 1^ inches in width, 

 for measuring the diameter of the scions (Figs. 82 and 

 83 J). Each notch bears a number corresponding to the 

 numbers on each compartment of the scion box.

This box is divided into eight equal compartments, into 

 which the scions are placed after being gauged ; the larger 

 compartment is used to carry the tools and accessories. On 

 the top of the wooden handle (Fig. 83 t t) a wooden block 

 is fixed, and a blade o b, having one extremity fixed on a 

 pivot o, round which it revolves, the other extremity is 

 provided with a handle b. A horizontal brass guide keeps 

 the blade flat on the wooden block, which is made of oak, 

 on the side of which are 16 inclined grooves, allowing the 

 making of both sides of the wedge for cutting scions of 

 different diameters. The numbers on each pair of notches 

 correspond to the numbers on the gauge. 



The grafting knife (Fig. 84) is of special construction. 

 On the blade is a small brass knob a, and a brass slide b, 

 which can be easily moved with the thumb ; a graduation 

 corresponding to that of the gauge enables the operator to 

 measure the distance between the knob and the slide. 



Comy's arrangement is used in the following way : The 

 scions are first sorted with the gauge and placed in each 

 corresponding compartment in the box, which is taken on
