front of the horses it would be much better, for then the locusts 

 would not be driven away from the machine and more would 

 be passed over and crushed. 



As the insects increase in size various roller-machines in 

 which the insects are obliged to pass between revolving 

 cylinders are very effective. They may also be destroyed in 

 large numbers by trampling with troops ot mares and flocks 

 of sheep; and by weighting down a fresh hide and dragging it 

 forward and backward over the locality occupied by a manga 

 of the insects. 



When the insects are still quite small and cover compara- 

 tively little surface; during cool, damp weather when they are 

 bunched; also when they gather on walls and sides of buildings ; 

 in close mangas among trees etc. very good results may be 

 obtained by the use of wire-flails, wooden paddles, shovels, 

 bags weighted with sand or earth, small bundles of tough twigs, 

 and any other device that may suggest itself and that can be 

 wielded by hand. Occasionally it happens that one man can do 

 more actual killing in a day by the use of one or the other of 

 these devices than at other times can be accomplished by one 

 or even two of the machines drawn by horses in twice the time. 

 These methods are applicable in gardens, quintas, vineyards, 

 groves, and other places where the large machines cannot be 

 used. They are also very effective during the first week of the 

 insect's life while it is still bunched, and where there are not 

 sufficient of them to Avarrant the use of the larger machines. 



Catching or bagging. — When it is desired to gather and 

 bag the insects for securing bounties or for other purposes, 

 this can be accomplished in a number of ways. Some of these 

 methods are the use of machines like the Carcarañá, and nets, 

 sheets of cloth, traps, fences, ditches, pits and the like. 



Each of these various methods is good in its own peculiar 

 way and under special conditions. The Carcarañá machine 

 comes into play where the insects arc gathered in fields of 

 wheat, alfalfa and like crops where they can climb above the 

 ground several inches. During evenings and early mornings 

 with horses, as shown in the illustrations, the machine is 

 rapidly drawn through the field and the insects captured. From 

 the machines they can be dumped into boxes, pits, or directly 

 emptied into bags. Several forms of these machines may be 

 devised, the only precaution that is necesar}^ is to see that they 

 are made to run as closely as possible to the ground because,
