In placing before my readers in the following pages the results of my twenty-five years’ experience of Rat-catching, Ferreting, etc., I may say that I have always done my best to accomplish every task that I have undertaken, and I have in consequence received excellent testimonials from many corporations, railway companies, and merchants. I have not only made it my study to discover the different and the best methods of catching Rats, but I have also taken great interest in watching their ways and habits, and I come to the conclusion that there is no sure way of completely exterminating the Rodents, especially in large towns. If I have in this work referred more particularly to Rat-catching in Manchester that is only because my experience, although extending over a much wider area, has been chiefly in that city, but the methods I describe are equally applicable to all large towns.
