as well as a wrong one even for driving locusts. This particu- 

 lar locust is not a great jumper at any time, as has already been 

 stated, and especially during the " saltona " stage is it that the 

 insect shows a deficiency in this respect when compared with 

 some of the smaller but more active species of grasshoppers. 

 By remembering this fact, and also that locusts are ver}' easily 

 confused and discouraged, better success can be had. It should 

 also be borne in mind that they cannot be urged forward very 

 rapidly. 



In driving them the person or persons performing the task 

 should be provided with some sort of banner or flag for urging 

 them forward. This should be of a color other than green — a 

 bright one being best, so as to be as conspicuous as possible. 

 This should be held in the hand and regularly waved toivard 

 the hoppers in the direction in which it is desired to drive them. 

 By keeping nearh^ or quite two meters behind and waving the 

 banner at regular intervals of at least a second or a trifle 

 more, apart, so as to give each insect an opportunity^ to gain 

 a footing, the entire mass will move forward very regularly 

 and quite rapidly. Should the person approach much nearer 

 and wave his banner more rapidh', the insects would become 

 confused and either dash about in all directions or hide in the 

 grass and refuse to move at all. Bv going at the work syste- 

 matically and in accordance with the insect's habits, even locust- 

 driving can be made quite a success as compared with hapha- 

 zard work. It is especially necessary that the above described 

 method be followed in driving the insects when they are among 

 grass or other short vegetation. It will also work quite satis- 

 factorily when the insects are among taller vegetation and in 

 open groves. It they should become confused while in such 

 situations, or in fact at any time, the}^ would cluster together 

 and refuse to be driven at all or the}' might stampede in an 

 opposite direction. They are much like sheep in this respect. 



Diverting invading mangas of voladoras. 



It very frequently happens that swarms or mangas of the in- 

 sect invade a district from some other region. When such is 

 the case, the flying insects may often be prevented from alight- 

 ing and inflicting their depredations. At such times fires built
