They move about in schools, along the 
sides of sandbars and work into the 
bays. When fishing deep with min¬ 
nows for crappies you often catch 
them. 
Often in the deepest holes in the 
lakes you will find the large perch, one 
hundred feet or more down. There, 
in the aquatic caves, you will find 
them; as also the black basses, for 
there, too, they sometimes retire in 
their season of hibernation. The perch 
of course, has one great enemy, it is 
the pickerel; also the pike and the 
muscallonge. They follow the perch 
schools industriously; for perch are 
their staff of life. It is for this reason 
that perch-like artificial minnows and 
live perch themselves on the hook prove 
such good bait for these fish.

Plate or films of two kinds are used 
in wild-life photography—ultra-rapid 
and panchromatic. The ideal plate or 
film for general use in animal photog¬ 
raphy is one which combines extreme 
rapidity with freedom from any ten¬ 
dency to fog. The chief bane of the 
wild-life photographer is under-ex¬ 
posure, as so many pictures are made 
in poorly lighted situations, and high 
shutter speeds must be used to stop the 
motion of rapidly-moving objects. A 
great increase in the sensitivity of 
photographic emulsions has been at¬ 
tained in recent years. The “rapid” 
plates of a few years ago are the rela¬ 
tively slow plates of to-day. The 
meaning of the word “rapid” in this 
connection has lost its significance, and 
the terms special rapid, extra-rapid, 
ultra-rapid, extreme speed and super¬ 
speed have in turn been introduced to 
designate the faster and faster emul¬ 
sions which have been produced. The 
result is that none of these terms have 
any precise meaning, and the universal 
adoption of the Hurter and Driffield 
system of plate speed numbers would 
be highly desirable. By this system 
super-speed and ultra-rapid plates have 
numbers between H & D 550 and 700, 
extra-rapid plates from H & D 400-500, 
special rapid plates from H & D BOO¬ 
STS, rapid plates from H & D 200-275, 
ordinary plates from H & D 100-175, 
and slow plates below H & D 100. 
Ultra-rapid plates and films are obtain¬ 
able from various makers, excellent ex¬ 
amples of these plates being the Im¬ 
perial Eclipse Ortho, Ilford Monarch 
and Wellington Xtreme, and of cut 
films the Eastman Super-speed Por¬ 
trait Film and Ilford Monarch Film.
