Ten miles' length of the screens were used for the protection of farms 

 and vineyards, and 1 6 miles* length for field operations. 



The most infected spot was the plain of Zaghonan, where, for some 

 days, as already stated, the combined, forces of all the sections had to be 

 collticted for the protection of gardens and vineyards situated in the long 

 valley, flanked on the northern and southern sides by brushwood swarm- 

 ing with yonny locusts. 



The screens furnished by the authorities are mostly manufactured in 

 Description of screens used Tunis, purporting to be facsimiles of the 

 m Tunis. article used in Cyprus. It is possible that 



they are made on the same model, but, judging from a personal inspec- 

 tion, the material must be very inferior. They are composed of strips of 

 cotton texture, 50 inches long, by 70 centims. broad, which stand no 

 wear and tear, and the strip of oilcloth bordering the upper edge is 

 very apt to crack, and thus cease to act as a barrier against the locusts, 

 who take advantage of the rent in the surface to crawl over the 

 screen.

well where firewood was plentiful and easily procured, but, as the 



trenches required re-filling from time to time with fuel, the men at
