is, however, a large amount of variation in the distribution of the monthly falls from year to year. No two consecutive years correspond in this respect. In 1876 a heavy storm, with great rainfall and snow, occurred in the month of October, but in 1875 and 1877 no such storm occurred. In 1875 many drenching showers occurred in the months of July and August, but none occurred at the same months of 1877. In general, however, no summer rainfall has ever been known of such extent as to dispense with the necessity of irrigation, or even to materially reduce the necessary amount. Great variability in the distribution of the fall over different months of the year is one of the characteristics of the climate. But whatever the distribution, it is never such as to affect this one conspicuous feature--that the season in which crops must have their chief growth and reach their maturity is the dry season. Connected with the irrigation of the Sevier Valley is a limiting condition, which rarely has to be considered in connection with the lands watered by the Bear and Weber Rivers, and which does not enter at all into the lands lying about Great Salt Lake. It is the dependence of climate upon altitude. There are lands along the upper portions of the forks of the Sevier which can be irrigated easily enough, but which are not cultivable for grain on account of the shortness of the summer and of the danger of frosts during the growth and ripening of the grain. This in turn is directly connected with the altitude. At the point where the Sevier leaves its main valley and enters the Pavant range, its altitude is 5,050 feet above sea-level. At Gunnison it is 5,150 feet. The altitudes of the San Pete Valley are approximately as follows: Feet. Manti 5,350 Ephraim 5,450 Moroni 5,500 Springtown 5,550 Mount Pleasant 5,600 Fairview 5,725 Fountain Green 5,650 Beginning at Gunnison and ascending the Sevier along its main course, the altitudes are as follows: Feet. Gunnison 5,100 Salina 5,175 Richfield 5,300 Monroe 5,350 Joseph City 5,375 Marysvale 5,600 Circle Valley 6,000 Taking the East Fork in Grass Valley: Feet.
