In southern Nevada there are 2 small irrigated valleys which were populated by Mormon farmers in the 1870's. With the building of Boulder Dam, Boulder City and the growth of Las Vegas the consequent increased need for dairy products resulted in the farmers of these 2 valleys to enter into the dairy business to a considerable extent in the last decade. With the introduction of dairying came the ensuing veterinary problems. In the 2 valleys, which are 40 miles apart, there was a total of 1,200 dairy cows. There were a few horses, a number of range cattle, 10 or 15 pigs, about 100 chickens and a few dogs. The prospects of inducing a veterinarian to live and practice this area were nil.
