Unless it has been established that the output of wells Nos. 1 and 2 can not be restored to something like the original volume (see page 5 of this report) a reasonable expenditure on these two may be productive of excellent results. There has been a great deal of waste of water in the Las Vegas Valley, a n d in a considerable measure this condition persists.
