THE COMMON VICTOKIAN LOCUST. 37 



the fungus contents of the tumbler, after a thorough im- 

 mersion take them out, and Hberate them ; repeat with 

 more locusts, and so on until the glass or vessel has been 

 emptied of its contents. Infect towards evening, and if 

 possible when there has been, or there are indications of 

 rain. Next, smear patches of grass where the locusts are 

 feeding with the fungus, also capture quantities of locusts, 

 and confine them in a box along with some of their 

 favourite food which has previously been smeared with 

 the fungus. Water fungus is not so effective in confine- 

 ment as bread fungus. The bread fungus is more easily 

 smeared over their food. Keep the box under conditions 

 as near to the natural as possible, as locusts will die if 

 too closely confined. In two or three days liberate the 

 lot among a swarm, and repeat again. 



To make Bread Fungus.

 fairly stale, and then grate it into a coarse powder. Place 

 a cupful into a basin, and add enough water to make a 

 watery paste (water must be previously boiled and cooled). 



ERRATUM. 



At page 36, line 28, instead of " A temperature of anything 

 from 70 per cent.," read "A temperature of anything from 

 70 degrees."

 disappeared. Catch young locusts in net, and bring them 

 to feed on the infected patches.
