gradually increase the quantities of milk and the intervals between 
feedings. Where a number of lambs are fed from a few bottles, it is 
convenient to have the vessel holding the milk heated and carried in 
a receptacle containing hot water, which keeps the milk at the proper 
temperature, so that it is not too cold when the last few lambs are 
fed. For a large number of lambs a barrel or tank equipped with a 
number of rubber nipples at the base is very convenient. 
Carelessness in any detail of feeding is likely to result in scours. 
The lambs should not be given too much. The temperature of the 
milk should be about 92° F. The bottles and nipples should be kept 
scrupulously clean. Scours are best overcome by boiling the milk 
for a few feeds after the trouble appears. Other common remedies 
successfully employed are the feeding of a small quantity of charred 
flour or a teaspoonful of lime water in the milk. For severe cases, a 
tablespoonful of castor oil is given. Boiled milk should not be fed 
continuously, as it causes constipation. 
Breeds.—Because of the intimate relationship which has existed 
between the farm sheep industry on the project and sheep production 
on the adjacent ranges, the breeds grown on the project are those of 
the surrounding range. In this section the popular range ewes are 
grades of the C type Merino and the Rambouullet or the crossbreeds 
of a long-wool buck (Lincoln or Cotswold) and fine-wool ewes. 
Some range bands contain three-fourths or more of the long-wool 
blood. As a rule, however, the range ewe that is most popular is 
the one carrying from one-half to three-fourths of fine-wool blood 
and the remainder long-wool blood. While there are some differences 
of opinion among the rangemen, the method followed by most of them 
is to use Rambouillet and long-wool bucks to keep the desired pro- 
portion of fine-wool and long-wool blood in the range band. The 
ewe lambs from these matings are kept to replenish the flocks, while 
the males are marketed as wether lambs. For the ewes which are 
to produce mutton lambs, black-faced bucks are used, and the entire 
lamb crop, both male and female, is marketed, usually early in the 
season. 
The difficulties of range sheep production have been so acute in 
recent years that only the more efficient of the range sheepmen have 
remained in the business. These men are usually progressive and 
quick to grasp opportunities for increasing their profits. One result 
of this is that the bucks now used are practically all pure-bred 
animals of the best quality obtainable. This has resulted in a 
strong demand for pure-bred bucks from the Minidoka project and 
has presented good opportunities to sheep growers on the project. 
The production of registered sheep was started on the project by 
the establishment of a flock of pure-bred Hampshires in 1911. At 
that time sheepmen were beginning to realize the value of this large
