THE IRRIGATION AGE. 



The Modern Wajon 



BUILT OF STEEL 



The only equipment that will stand the climate of the 

 irrigated district, is made of steel. Vou know the reason. 

 Wood dries out, becomes useless, and the machinery 

 falls apart. 



Davenport Roller - Bearing 



Steel Wagons 



are THE wagons for the "Dry Farming" country. Not 

 affected by the climate. Stronger, lighter draft and more 

 durable; outlast several wooden wagons. 



Built of steel I-beams, Channels and Angles, solidly 

 riveted with large steel rivets, put in hot, making the gear 

 parts practically one piece. 



Nothing to Dry Out 



No bolts to become loose and nuts to rattle off on 

 account of parts shrinking or drying out. The DAVEN- 

 PORT is constructed like the modern steel railroad 

 bridge. Trussed and braced to withstand all strains. Built 

 for the heaviest lifetime service. 



No Tires to Reset 



It makes no difference what the climate is, it does not 

 affect the wheels on the DAVENPORT. They are made 

 with a tension, each spoke carrying its share of the load 

 all the time, whether it is on the top, bottom or side of the 

 wheel. The spoke heads are countersunk in the tire; 

 headed and shouldered in the hubs. The strongest wheels 

 ever put on a wagon. No split felloes or cracked hubs. 

 No repair bills to pay. 



Roller Bearings 



The Roller Bearing 



30% to 50% Lighter Draft 



It is a fact, that if it were not for the ROLLER BEARINGS, 

 the automobile of today would be impossible. You know that 

 ROLLER BEARINGS reduce the draft on machinery of all kinds. 

 Here is your chance to get these advantages on

COST OF FILLING SILO. 



A Nebraska farmer figures on the cost of silage: 



"The drouth has caused my hay crop to be very 

 short, but I do not know whether I can afford to use 

 the corn for ensilage or not. What does it usually cost 

 per ton?" 



The cost of ensilage per ton depends very largely on 

 the value of the land, and the kind of corn crop that is 

 grown. We have known of instances where it required 

 but eight acres to fill a hundred-ton silo, and other in- 

 stances where it would take at least twenty-five acres. 

 For this reason the cost of filling a silo depends on the 

 amount of forage per acre more than on the cost of labor 

 involved, which is one of the smallest items. 



Prof. Haecker, of Nebraska Station, after carefully 

 taking into consideration all the factors which enter into 

 the production of corn estimates the cost of putting 

 up a ton of ensilage at $1.95. Some Iowa farmers have 

 computed the cost as low as $2.15 per ton; others have 

 gone as high as $2.49. 



Prof. Mumford, of Illinois, has computed the cost of 

 ensilage, figuring the value of corn at 35 cents per bushel, 

 to be approximately $2.75 per ton. On an average it will 

 cost you from $2.00 to $2.50 per ton for filling your silo. 

 This is a very small price to pay for ensilage when com- 

 pared with hay and other feeds, which will range from 

 $10.00 and up per ton. 



MOUNT M'KINLEY REGION. 



The great crescentic sweep of Alaska's southern coast 

 line is broken at its most northerly point by Cook Inlet, 

 named after the" famous explorer of the eighteenth cen- 

 tury, an embayment which penetrates the mainland for 

 nearly 200 miles. The drainage basin tributary to Cook 

 Inlet is cut off from the Yukon and the Kuskokwim wa- 

 ters on the north and west by a chain of rugged moun- 

 tains known as the Alaska Range, at the heart of which 

 towers majestic Mount McKinley, the highest peak of 

 North America, and its sister peak Mount Foraker. Pre- 

 vious to 1902 this region constituted a great block of un- 

 known territory. When in 1898 the United States Geo- 

 logical Survey began its task of exploring, surveying, and 

 studying the mineral resources of Alaska, the first work 

 was of necessity merely exploratory, for until the larger 

 features of drainage and relief had been outlined it was 

 impossible to plan topographic and geologic surveys. The 

 demand of the prospector was for maps and information 

 to guide him in hazardous journeys. From 1898 to 1902, 

 therefore, the Alaskan work of the Geological Survey was 

 largely a series of reconnaissances, covering wide areas 

 and outlining the larger physiographic features a skele- 

 ton to be gradually filled in by detailed mapping. But 

 the Mount McKinley region remained untouched. Plans 

 for its survey had been considered as early as 1899, but 

 it was not possible to put them into effect until 1902. 



"The Mount McKinley Region of Alaska," by Alfred 

 H. Brooks, just issued by the Geological Survey as Pro- 

 fessional Paper 70, describes this work of early explora- 

 tion of a vast tract of territory absolutely unknown and 

 incomparably wild. The report is a large volume de- 

 scribing the geologic, geographic, and mineral resources 

 of the region, but Mr. Brooks' brief description of the 

 trip itself is a tale of real adventure. In 105 days the 

 party, consisting of 7 men, penetrated 800 miles of an 

 unknown wilderness with almost impassable swamps, un- 

 fordable rivers, and lofty snow-covered mountains. These 

 men depended largely on their guns for provender, but 

 finally accomplished their purpose of striking through 

 the Alaska Range and coming out into the interior Yukon 

 valley, a feat which was looked upon by the natives as 

 impossible. Starting from Tyonek on Cook Inlet on June 

 2, the party struck inland. 



"Although the Indians and traders agreed," says Mr. 

 Brooks, "that with good luck we might be able to get 

 across the Alaska Range, no one believed it possible that 

 we could extend our work to the Tanana, much less to 

 the Yukon. It was the general expectation that the party 

 would return to Cook Inl^t in the fall. This might have
