THE IRRIGATION AGE. 



IDAHO, "THE GEM OF THE MOUNTAINS." 



(Continued from page 227.) 



The nights are generally cool and comfortable and dur- 

 ing the hottest weather blankets will be needed for cover 

 before the morning sun appears. In the Lewiston coun- 

 try there is an abundance of rainfall eight months in 

 the year. Commencing about the middle of November, 

 ihe rainy season sets in and continues, usually, until 

 about the middle of July. From this time on until 

 .about the middle of November usually but little rain 

 falls, which gives the farmers ample time to take care 

 of their crops. Scarcely a month passes in this section 

 in which the farmers are not able to plow at least a 

 part of the time. Located at different points over the 

 state are found natural hot springs, the waters of which 

 contain various medical properties. No matter what the 

 affliction, there seems to be a spring wherein are con- 

 tained the necessary ingredients to effect a cure. The 

 picturesque scenery of the Idaho mountains is unsur- 

 passed and is attracting the attention of many people 

 who seek health, rest, refreshment in the mountains dur- 

 ing the summer months. The headwaters of the Snake 

 river have already becomes the home of many people 

 from eastern cities, who have erected beautiful cottages 

 along the streams and who spend their summers breath- 

 ing the health-giving air of this country, where the sun 

 shines, in a cloudless sky, 300 days in the year. 



The region covered by the State of Idaho has long 

 been a favorite haunt for all kinds of wild animals that 

 inhabit the mountain country of North America. The 

 great range of mountains, that follow each other in close 

 succession over the state, with the broad timbered slopes, 

 cut by deep canyons and ravines through which flow 

 .sparkling streams of clear, spring water, opening into 

 extensive lakes in many places, is an ideal spot for all 

 fur-bearing animals and large game. The low lands are 

 crowded with great numbers of wild fowls, and the 

 streams are filled with trout. 



Idaho is becoming famous for its extensive orchards 

 and fruit products. The horicultural industry has 

 made rapid strides and is now the most prominent 

 branch of the agricultural resources of the state. 



The valleys can not be excelled by any region in 

 the United States for the production of apples, peaches, 

 pears, apricots, plums, prunes and grapes; for sunshine 

 and soil all combine to produce a growth and impart a 

 flavor that is unexcelled anywhere. 



Boise, the capital of Idaho, with a population of 

 16,000, lies in a beautiful valley of genurous dimensions, 

 fine resources and unlimited possibilities. It is located 

 on the Oregon Short Line Railroad, 505 miles from 

 Portland and 435 miles from Salt Lake City this lat- 

 ter city being the supply point for all the rich mining 

 camps and towns in southwestern Idaho and over 

 $2,000,000 worth of merchandise is hauled out by wagon 

 each year from the wholesale houses there to the var- 

 ious mining camps. The water used for domestic pur- 

 poses is obtained from artesian wells located in the foot 

 hills above the city, and no system could be devised that 

 would furnish a better supply of pure water. The hot 

 water used for domestic purposes is also supplied from 

 artesian wells that provide water heated to 170 degrees 

 Fahrenheit. This hot water, besides being piped over 

 the city and delivered to buildings and residences the 



same as cold water, is used for heating purposes; thus 

 providing Boise with a convenience enjoyed by no other 

 city in the United States. The Natatorium, a bathing 

 establishment whose plunge and private baths are sup- 

 plied with hot water from these artesian wells, is the 

 pride of Idaho's capital, these waters, as shown by gov- 

 ernment analysis, having rare medicinal qualities. 



America has now triumphed over Egypt and India 

 in holding what will soon be the largest irrigated tract 

 of desert land in the world. That is what is known as 

 the Twin Falls country, in the State of Idaho. The 

 ultimate area under irrigation when the entire Twin 

 Falls project shall have been completed, will be 1,350,- 

 000 acres. 



THE NEW HOPPER COOLING PLAN FOR COOL- 

 ING GASOLINE ENGINES. 



The well-known principle of maintaining a moderate 

 temperature on gasoline engines has heretofore been through 

 the use of a large water tank, or water pump, which has the 

 disadvantage of increasing the weight, of being cumbersome, 

 and of requiring a great deal of water for cooling. 



It is necessary in a gasoline engine to have a circula- 

 tion of water around the cylinder to prevent overheating 

 and to maintain a moderate temperature to avoid ignition 

 of the fuel before the proper time; this is why the water is 

 used for cooling. 



The new hopper principle consists of making a box-form 

 hopper of cast iron, placing it over the cylinder, holding the 

 water directly over the cylinder for cooling purposes. The 

 principle of the teakettle again comes into effect. The open 

 top of the cylinder and the open hopper permits evaporation ; 

 the steam condenses quickly, and comes in contact with the 

 open air immediately, consequently water exposed to open 

 air cools twenty to thirty times faster than water enclosed 

 in a jacket, for that reason a hopper-cooled engine can be 

 cooled with from twenty to thirty times less water than is 

 used with the average engine using a water tank. 



It reduces the weight of the equipment; saves the water; 

 avoids draining or handling a large amount of water in

cold weather, and consequently, avoids the usual danger of 

 freezing. 



We show herewith a Witte hopper-cooled gasoline en- 

 gine, made by the Witte Iron Works Company, Kansas City, 

 Mo., which illustrates the simplicity of the hopper-cooling 

 plan. In this case the hopper is built separate from the cyl- 

 inder, so that it can be removed. The company will furnish 

 a plate in exchange for the hopper any time the purchaser 

 may desire to use the water tank principle in the place of 

 the hopper. The side of the hopper is also arranged for pipe 

 connections. The hopper-cooled engine has become very 

 popular, and we are sure that article is of interest to all of 

 those who contemplate the purchase of a gasoline or kero- 

 sene engine. Whether the engine is used in a shop or for 

 outdoor work, the principle and the convenience has the 

 same advantages. 



Anyone expecting to buy a gasoline engine will do well 

 to investigate all improvements, and in particular to write to 

 the above company for description of their hopper-cooled 

 engines.
