IRRIGABLE LANDS OF THE SALT LAKE DRAINAGE SYSTEM. 119 
will the entire alluvial plain of the Bear be served, but the valley of the 
Malade, as far as Oregon Springs, and the valley which extends from Little 
Mountain to Connor's Spring. After deducting from these areas the land 
along the margin of the lake that is too saline to afford hope of reclamation, 
there remains a tract of 214 square miles. One-tenth of this is now in use, 
being in part watered by Box Elder Creek and other small creeks, and in 
part cultivated without irrigation. 
In the following table are summed the agricultural resources of that 
portion of the Bear River drainage basin which lies in Utah:

The entire area of the Bear River District is about 3,620 square miles, 
24 per cent. being now under cultivation, and over 15 per cent. susceptible 
of cultivation. 
The Weber River runs with a general northwesterly course from the 
Uinta Mountains to Great Salt Lake, entering the latter at the middle of its 
eastern shore. "The Ogden is its only important tributary. At the foot of 
the mountains it enters Kamas Prairie, in which it can be made to irrigate 
a few square miles. Thence to Hennefer, a distance of 30 miles, it is 
continuously bordered by a strip of farming land about one-third of a mile 
broad. Then it passes a series of three close canons—in the intervals of 
which are Round Valley, with a few acres of land, and Morgan Valley, 
with 7 square miles—and emerges upon its delta plain. Within this 
plain are no less than 219 square miles of farming land, of which about 
two-fifths are now in use. A part is unwatered, a part is watered by the 
Ogden River and by a number of creeks, and the remainder is watered by 
the Weber. ‘To serve the higher portions of the plain a great outlay would 
be required, and 1 am of opinion that the highest levels cannot profitably
