206 DESTKUCTIVE INSECTS OF VICTORIA* 



Simple Coal-Oil Pan. 



{See Figs. 20 and 21.) 



A good and cheap pan is made of ordinary sheet iron, 8 feet long, 

 11 inches wide at the bottom, and turned up a foot high at the 

 back and an incli high at the front. A runner at each end, 

 extending some distance behind, and a cord attached to eacli front 

 corner complete the pan at a cost of about 6s. We have known from 

 7 to 10 bushels of young locusts caught with one such pan in an after- 

 noon. It is easily pulled by two boys, and by running several together 

 in a row, one boy to each outer rope, and one to each contiguous piir, 

 the best work is performed with the least labour. Longer pans, to be 

 drawn by horses, should have transverse partitions (Fig. ) to avoid 



spilling the liquid; also more runners. The oil may be used alone so 

 as to just cover the bottom, or on the surface of water, and the insects 

 strained through a wire ladle. When the insects are very small, one 

 may economise in kerosene by lining the pan with saturated cloth, but 

 this becomes less efficient afterward, and frames of cloth saturated with 

 oil do not equal the pans. Where oil has been scarce, some persons 

 have substituted concentrated lye, but when used strong enough to kill 

 it costs about as much as the oil The oil pans can be used only when 

 the crops to be protected are small. Small pans for oil, attached to an 

 obliquing pole or handle, do excellent service in gardens. 



The Price Oil Pan. 



{See Fig. 22.) 



This contrivance was invented by Mr. A. A. Price, of Rutland, 

 Humboldt County, Iowa ; he sends the Commission the following 

 description of a coal-oil pan to be drawn on runners, and Avhich was 

 used with much success in America: — 



Take a common board from 12 to 16 feet in length for the foundation 

 or bed-piece. Make a tin trough 4 inches deep, 6 inches wide, and as 

 long as required. Divide the trough into partitions by means of strips 

 of tin, so that each partition is a foot long, thus avoiding the spilling 

 of oil. Back of this place a strip of tin 16 inches wide and as long as 

 the trough. The back must be firmly secured by braces running down 

 to the front edge of the board. Under all this place three wooden 

 runners 3 feet long, and shod with iron, for the trough to ride on. Fill 

 the pan half-full of water, and then add a small quantity of kerosene, 

 suflficient to cover the water. A horse may be hitched to the machine 

 by fastening a rope to the outside runners. The lightness of the 

 machine will allow of its being used on any crops.
