one-sixth its weight of oatmeal. Obtain the sawdust fresh from under the
saw, without bits of stick in, as these would be liable to get into the
teeth of the trap and stop them from closing. Where you see the runs put
a handful in say about 30 different places, every night, just dropping
the sawdust and meal out of your hands in little heaps. That means 30
different heaps. Do this for four nights, and you will see each morning
that the sawdust is all spread about. Now for four more nights you must
bury a set trap under every heap of sawdust. Thus you will have 30
traps, on each of which there is a square centre plate; you must level
the sawdust over the plate with a bit of stick, and set each trap as fine
as you can on the catch spring, so that the weight of a mouse would set
it off. They will play in the sawdust as usual, and you will have Rats
in almost every trap. You will find that this plan will capture a great
many of the Rodents. I have trapped as many as 114 in one night in this
way.

In time, however, the Rats will cease to go near sawdust. Then you must
procure a bag of fine soot from any chimney sweep, and you will find that
they will go at the soot just as keen as they did in the first instance
at the sawdust. When they get tired of soot (which they will in time)
you must procure some soft tissue paper and cut it fine, and use that in
the same way as the sawdust and the soot. You can also use light chaff
or hay seeds with the like result.

I must not omit to tell my readers to always trap Rats in the night, and
to go very quietly about it, for if you make much noise they will give
over feeding. You must not go about with too big a light whilst
trapping. You should stay at the building from dark until midnight, and
every time a Rat is caught in the trap you should go with a bull's eye
lamp, take it out of the trap or kill it, and then set the trap again, as
