144 DESTRUCTIVE INSECTS OF VICTORIA: 



from place to place it is the best apparatus that has yet been produced. 

 It is desired to have the stay-rods and Avindlass attached to a turn-table, 

 so that the tent could be taken off one tree and put upon another with- 

 out moving the waggon ; by this arrangement three tents could be 

 operated by the one apparatus without any loss of time. It might also 

 be desirable to mount this apparatus upon runners, like those of a sled, 

 but placed as wide apart as the trees would admit. 

 This fumigator has not been patented up to date. 



The Titus Fumigator. — This apparatus was devised by Mr, L, H. 

 Titus, of San Gabriel, and is especially designed for operating on tall 

 trees. It is shown in Fig. 18,, and consists of four corner posts 

 made by bolting together two boards in such a manner that they form a 

 right angle with each other ; at the upper ends these posts are connected 

 by cross-pieces formed of boards bolted together like those forming the 

 corner posts. Two of these cross-pieces are longer than the other two, 

 and are placed on opposite sides of the frame ; they are connected near 

 the middle by two cross-pieces, between which is placed the roller upon 

 which the tent is to be wound when being drawn off the tree. These 

 various cross-pieces are braced. 



The lower end of each of the rear corner posts is rigidly attached to 

 an axle, on the outer end of which a light wheel is placed, while the 

 inner end is connected with the corner post by an oblique brace. The 

 lower end of each of the front corner posts is attached to the middle of 

 an axle having a light wheel at each end ; the post is attached to the 

 axle by an iron bolt which permits the wheels to be at the same moment 

 turned, the one forward and the other backward, like the forward wheels 

 of a waggon or buggy. By means of this arrangement the fumigator 

 can be turned about in a circle. The front and rear corner posts on 

 each side of the fumigator are connected with each other by a cross-piece 

 extending from one to the other, and strengthened by braces which 

 extend obliquely from the cross-piece to the posts. When this 

 fumigator is in use the front and rear cross-pieces shown in Fig. 18., as 

 extending from the posts on the one side to those on the other are re- 

 moved, so as to permit the frame to pass either forward or backward 

 over the trees. 



The top of the tent is attached by three ropes to the roller, while to 

 the lower edge of the tent are attached four ropes, placed at equal dis- 

 tances from each other ; each of these ropes passes through a pulley 

 attached to a frame near each upper corner, and the end of the rope is 

 attached to the lower edge of the tent at the place where the opposite 

 end of the same rope is attached. For winding the tent upon the roller 

 an endless rope is used ; this passes around a grooved wheel at one end 

 of the roller and is carried through a pulley near the upper end of one of 

 the rear corner posts ; from this point it passes to and around a grooved 

 wheel fastened to the cross-piece near the lower end of this post, and 

 this grooved wheel is operated by a crank. 



In taking a tent off of a tree, each of the corner ropes is pulled through 

 its pulley, drawing the bottom of the tent upward, thus turning the tent
