of the land. (Fig. 19.) A satisfactory arrangement is to build a 
long, low shed with board partitions dividing it into compartments 
7 feet high, 7 feet wide, and 11 feet long. These dimensions can be 
varied if desired, although it is not advisable to reduce them. The 
front and back are of wire netting, preferably H-inch mesh, No. 15 
gauge. A door is constructed in the front of each pen in the same 
manner as described for breeding pens. It is well also to build a 
small nest box, so that the occupant of the pen may be sheltered 
from extreme weather. 
The kind of floor is determined by the soil and the length of 
time the pens are to be used. On light, sandy, well-drained soils 
a dirt floor is satisfactory. It should be from 2 to 6 inches higher 
than the outside surface of the ground. Dirt floors should be 
renewed frequently by removing the contaminated surface down 
to clean soil and then refilling with fresh sand or fine gravel and 
earth. It should be remembered, however, that where dirt floors 
are used the wire netting and the side partitions will have to be sunk 
from 2 to 3 feet below the surface, in order to prevent the foxes

from digging out. This is not necessary with board or cement 
floors. 
When the level of the floor in the pen is above the ground, 
board floors are sometimes used. However, if too low, such floors 
may harbor rats and rot quickly. They should be raised some dis- 
tance off the ground to facilitate cleaning under them. 
Cement floors are satisfactory when an artificial floor is required 
and can be built on the ground level. They are generally used in 
pens intended for sick or injured animals. These floors are easy 
to clean, sanitary, rat-proof, and comparatively inexpensive if a 
supply of gravel or sharp sand is available. 
It is essential on a large ranch to have a group of isolated pens in 
which sick or injured animals, or those newly purchased, can be 
quarantined. 
A temporary pen, used for the purpose previously described, may 
be 10 feet long. 6 feet wide, and 4 or 5 feet high. A frame of 2 by 
4 material is entirely covered with netting of H-inch mesh, No. 15 
gauge wire, and s$ small door placed in the front. As the pen rests 
directly on the surface of the ground, it is well to cover the floor wire 
with sand or fine gravel and earth. This material should be re- 
moved frequently and clean dirt substituted to prevent the soil from 
becoming contaminated. A small nest box can be placed inside the
