shut-off and the supply is always fresh. All pipes in this system
slope to one low point, so that even in zero weather, we can water and
drain the pipes without difficulty. The bathing system is worked on the
same plan in the aviaries, but we disconnect this part of the system in
the extreme weather.

The entire plant is raised about 18 inches off the ground at all
points, as a protection against rats. All entrances have heavy screen
doors as well as wooden ones, which work with weights to always keep
them shut. In this way, rats are kept out, and any pigeons which may
get loose inside the halls, are always caught. Rats are the greatest
menace to successful squab raising and too great precautions cannot be
taken.

[Illustration: DIAGRAM OF PASSAIC VALLEY SQUAB FARM]

You will note on looking over diagram of plant that sections 1, 2, 3
and 4 are connected by granary only. This feature could be considerably
improved by a hall connecting the four sections at the other end. Then
again, there are no windows on the north side of all four sections, and
although this was done to keep out cold, it could be improved with a
few windows for greater light.

Altogether I feel that the plant is as near to a model plant as can be
found, and being within 20 miles of New York City and eight miles of
Newark, the best markets are always available.

I am not describing this plant to discourage any one starting in a
small way in a back yard, barn, or outhouse; but I wish to show the
possibilities within the grasp of any one to establish a real
profitable business of his own.

In the next chapter, I will handle the situation from the beginner's
standpoint.

CHAPTER III.

THE FUNDAMENTAL REQUIREMENTS FOR SUCCESSFUL SQUAB RAISING.

Good squabs can be raised in any structure, free from dampness, that
has sunlight and can be protected from rats. Any shed, outbuilding, or
chicken coop can be turned into a first-class pigeon pen with little
difficulty. First, the building must be made habitable by patching all
cracks and leaks in roof. If the locality is subject to cold wind, snow
and ice, attention must be given to sides and floors. The floors,
particularly, should have no holes, and double floors are a decided
asset for the northern breeder.

Making the house rat-proof, is very important, and the best method I
know is to raise the building on posts, not less than 15 inches from
the ground at all points. Line the posts with t
