ment, which may be shortly described. The catting .apparatus consists of the 
combination of a chisel-knife A, and a hook-knife B (Figs. G7 & G8) ; the latter

has a slot, a, in its shaft, in which a rivet attached to 
the chisel-knife slides when the knives are opened 
or closed ; when the knives are drawn together in the 
operation of cutting, by pressure in the direction of the 
shaft D, the screw, or bolt, which attaches the hook- 
knife B to the handle C, slides along the curved slot b, 
towards the axis upon which the chisel-knife A 
revolves, so that the lever power by which the 
blades are forced together is continually increased 
as the operation proceeds. The chisel-knife A is 
attached to the handle C by a rivet, which is sta- 
tionary at I, the end of the shaft works against a 
spring on the back of the handle (see g, Fig. 68) 
so that when the operation is complete, the knile 
is thrown back to its position, and the spring then 
presses on the surface I, so as to hold the knives open. The handle C is 
attached to a wooden shaft, D, by a bolt and tap, and an extension shaft, E, 
can be added if required. To this a saw, F, can be attached if desired. This 
implement was tried on some trees in the Exhibition grounds, and did good 
work, cutting branches 2 inches in diameter. 
A cheaper and more simple implement was shown by E. S. Lee and Co. 
Rochester, New Jersey, viz., Waters' Improved Tree Primer (Fig. 69). The 
cutting blade is pivoted on the neck of the fixed blade, and worked by a lever 
handle from the bottom of the shaft. The fixed blade, which is hooked, is placed 
over the bough, and by working the lever handle, a series of chops are made on 
the under side of the branch. 
The machinery for facilitating domestic processes was nu- 
merous, varied, and ingenious'; but I am conscious that already 
my notes have extended beyond reasonable limits; suffice it,
