How are you going to keep 

 these down on the farm? 



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 known as the 



" Liverpool" Virus for Rats and Mice, produced by Evans Sons 

 Lescher & Webb 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, 

 Hanover Street, Liverpool, and 60, Bartholo- 

 mew Close, London, E.G. 1, 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 

 correspondence as to procedure in special circumstances. 

 "Liverpool" Virus is not a poison and therefore overcomes 

 the acknowledged difficulty with other exterminators. 



The Virus may also be obtained from Chemists.
