secured. Above Panguitch the amount of arable land is not great, and the 
danger to crops is increased. In Grass Valley there is a magnificent 
expanse of fertile arable land, but there can be no question that a large 
portion of it is so liable to killing frosts in August, or even in July, that the 
cereals cannot flourish there. The lower portion of the valley, near the 
head of East Fork Canon, is more hopeful, and it is probable that a large 
majority of crops planted there will mature, though occasional damage may 
be reasonably looked for. The general result may be summarized as 
follows: Below 6,000 feet crops may be considered as safe from serious 
damage by frosts. From 6,000 to 7,000 feet crops are liable to damage in 
a degree proportional to the excess of altitude above 6,°00 feet. Above 
7,000 feet the danger is probably such as to render agriculture of little 
value to those who may pursue it. 
The climate has shown in past times a longer period of variation than 
the annual one. Panguitch was settled once in 1860, but was abandoned 
on account of the destruction of crops by the frosts. The settlement was 
renewed in 1867, and again abandoned, in consequence of the attacks 
of Indians: It was settled a third time in 1870, and, though crops have 
occasionally been injured, the agriculture has on the whole proved remn- 
nerative. 
Let us now look at the irrigable lands of the Sevier and its tributaries. 
Above the town of Panguitch, on the South Fork, there is a considerable 
area of arable land, which could be easily reached by canals from the main 
stream and below 7,000 feet altitude, but for want of a detailed survey it 
is impossible to do more than guess at the area. I think, however, that 
8,000 acres would be the maximum limit. This portion of the valley is 
liable to killing frosts, though during the last three years it has not suffered 
from this cause. In the long run, I believe agriculture will not prove 
remunerative here. From Panguitch northward to the head of the Pan- 
guitch Canon, a distance of 18 miles, is a broad valley, averaging 5 miles in 
width, a very large portion of which is irrigable, provided the water supply 
is adequate. At least 24,000 acres may be cultivated without resort to 
anything more than the usual methods of distributing the water; but not 
the whole of this area is fertile. The greater part of the area of Panguitch
