The Farmer's Costly Guest. 



The Wages the Rat Extorts. 



Farmers' and agriculturists' indignation is aroused by the 

 announcement that rats are causing damage to the extent of 

 over one million pounds per annum in the British Isles on 

 farms alone. 



In our huge granaries, stores, and provision shops, as 

 well as on board nearly every cargo vessel, scores 

 of millions of rats are nibbling and gnawing at 

 our dearly bought and jealously guarded food 

 stores. 



Every day thousands of rats are added to the 

 hordes that are continually gnawing at the heart 

 of the nation, and at the present moment there 

 are probably over 50 million rats in the British 

 Isles alone. 



They are everywhere, nibbling not only grain, 

 but cheese, butter, eggs, fowls, and meat, and 

 also gnawing and utterly destroying textiles and 

 clothing and damaging thousands of pounds 

 worth of property. 



The only means to employ that will ensure 

 a wholesale destruction is the use of a disease-producing 

 germ such as has been proved effective in innumerable 

 tests made at the Runcorn Laboratories of Evans Sons 

 Lescher & Webb Ltd. 



These germs or disease-producing bacteria are ki 



the 



LiA^erpool Virus for Rats and Mice, produced by Evans Sons 

 Lescher & \\'ebb Ltd. It is virulent and particularly active 

 and when infection is introduced amongst a colony of rats 

 by applying the Virus to suitable bait, the whole colony is 

 affected and exterminated, the rats communicating a fatal 

 intestinal disease to one another and in most cases being 

 speedily obliterated. The Virus has no effect 

 upon human beings or domestic animals, and the 

 disease produced is of a nature that compels 

 the rats or mice to come into the open air to 

 die, thus causing no unpleasant smells. 



Liverpool Virus for Rats is supplied on bait 

 ready for use in 2/6 and 6/- tins, for Mice in 1/6 

 tins. In this form the Virus involves no trouble 

 in use, it can, however, be obtained without bait 

 if required, in 2/6 and 8/- tubes for Rats, and 

 1/6 tubes for Mice. 



Evans Sons Lescher & Webb Ltd., 56, Han- 

 over Street, Liverpool, will supply at the above 

 prices postage paid, and will gladly advise 

 any large users or institutions on any matter connected 

 with the extermination of rodents, and welcome corres- 

 pondence as to procedure in special circumstances. 



The Virus may also be obtained from Chemists and all 

 branches of Boots. ^ i" i
