THE IRRIGATION AGE. 



THE SECOND-FOOT OF WATER. 



"Second-foot," as defined by the United States Geo- 

 logical Survey, is an abbreviation for cubic foot per sec- 

 ond and is the unit for the rate of discharge of water 

 flowing in a stream 1 foot wide, 1 foot deep, at a rate of 

 1 foot per second. It is generally used as a fundamental 

 unit in measurements of stream flow. 



"Second-feet per square mile" is the average number 

 of cubic feet of water flowing per second from each 

 square mile of area drained, on the assumption that the 



Genuine Navaio Blankets 



My business is done directly with the Navajo Indians, whose 

 reservation is near Aztec. I make trips to the reservation 

 and purchase the best in the line of Navajo rugs and blankets 

 direct from the Indian weaver. I have no middleman to pay. 

 Why pay $20 to $50 for a Navajo rug or blanket in a Chicago 

 store when I can sell you the finest quality from $5 to $35, 

 depending on size. If not satisfied after examination I 

 will refund your money, and I refer to the Citizens Bank of 

 Aztec as to my responsibility. Before buying a Navajo rug or 

 blanket write me telling me size you want and get my prices.

run-off is distributed uniformly both as regards time and 

 area. 



An "acre-foot" is equivalent to 43,560 cubic feet and 

 is the quantity required to cover an acre to the depth of 

 1 foot. The term is commonly used in connection with 

 storage for irrigation work. 



One second-foot flow equals 7.48 United States gallons 

 a second, '448.8 gallons a minute, or 646,317 gallons a day. 

 As a California "miner's inch" equals 0.187 gallon a sec- 

 ond, there are 40 California miner's inches in 1 second- 

 foot. 



WATER POWERS OF GREEN RIVER. 



150,000 Theoretical Horse Power in Basin of Main Tribu- 

 tary to Colorado River. 



The waters of Green River, the main branch of the 

 Colorado, and its tributaries, while possessing large possi- 

 bilities for the development of power, are practically un- 

 used except for irrigation. Theoretically it would be 

 possible at the present time, according to the United 

 States Geological Survey, by utilizing known storage sites, 

 to develop about 1, 500,000 horsepower in the basin of the 

 Green. From Wells, Wyo., to the Wyoming state line, 

 a distance of 225 miles, the stream has an average fall of 

 11 feet to the mile; and from the Wyoming state line to 

 the mouth of Minnie Maude Creek, a distance of 200 miles, 

 the average fall is 7 feet to the mile; the total fall is 

 3,875 feet. 



An Auto Wagon Travels 

 At Less 

 Expense 

 Per Mile 

 Than a 

 Driving Team 



N International Auto Wagon costs 

 little if any more than any good 

 driving team, buggy and light wagon, i 



With reasonable care it will last as long as the team will stand up to the 

 work of the road. The maintenance cost of the International Auto Wagon 

 is low because of the small expense necessary to keep up solid tires. I 

 About a cent and a half a mile for gasoline and oil, a cent a mile for 

 grease and possible repairs say three and a half cents a mile for all 

 maintenance is considerably less than the usual cost of a road team. 



An International Auto Wagon 



will go anywhere that a team can go and will travel two or three times as 

 fast. It costs nothing to keep when not working. It is a steady, every- 

 day, all-day-long worker, with power enough to meet any emergency. It 

 is simple any member of your family can learn to drive it. The 

 brakes are powerful safe on any hill. The springs are resilient, making 

 the car easy-riding. There is an auxiliary spring to take care of heavy 

 | loads. 



The International Auto Wagon is quickly converted from a wagon 

 L:for light hauling to a pleasure car, by the addition of an extra seat in the 

 ' back. A top is furnished for protection from sun and storm. 



Give us an opportunity to show you how many business trips this car 

 [ will make for you, how much pleasure it will give your family, and 

 at what little expense it will do it. A postal to the nearest branch 

 bouse will bring catalogues and full information.

MANITOBA HOMESTEAD 

 ENTRIES. 



Entries filed for homesteads in the 

 province of Manitoba during the 

 month of July, 1912, were 261 in num- 

 ber, showing an increase of 69 over 

 the same month last year, which, in 

 turn, exceeded 1910 in homestead en- 

 tries by 22. These figures are pointed 

 to by officials of the Dominion Land 

 Department as indicating a steady 

 growth in this branch of the depart- 

 ment's activities and a growing ap- 

 preciation by immigrants to Western 

 Canada of the opportunities afforded 

 homeseekers in Manitoba. "The class 

 of people takine: up these homesteads 

 is all that could be desired the best 

 in the land," says L. Rankin, Dominion 

 land agent at Winnipeg. "Many of 

 them are well-to-do, practical farmers 

 from the east, who have sold out down 

 below, and are prepared to take ad- 

 vantage of an opportunity to branch 

 out on a larger scale. Others are good, 

 industrious foreisrners, all of whom 

 can at least read and write, and are in 

 every other respect qualified for good 

 citizenship."

usually be selected of such capacity 

 that the same power will be required 

 to run each of them, and hence an 

 engine purchased of just sufficient 

 power to run them. Manufacturers 

 of power driven machinery give in 

 their catalogues the capacity of their 

 machines and also the amount of 

 power required to run them. 



It is often the case on a large 

 farm that it is more economical to 

 have two engines of different power. 

 For instance, have one engine for 

 pumping water, turning the grind- 

 stone,, driving shop tools, etc., and a 

 larger one for grinding feed, cutting 

 ensilage, etc. Colorado Agricultural
