The sorg:hum plants thus have the advantage over the corn plant 

 under any climatic condition that would tend to bring about a loss of 

 water from these plants. The sorghums have, in the first place, as com- 

 pared to the corn plant, only one-half the leaf surface exposed for the 

 evaporation of water; and in the second place, they have a root system 

 which, judging from the number of secondary roots, would be twice as 

 efficient in the absorption of water from the soil. As a result of this 

 advantage the sorghum plants are able to absorb water from the soil 

 as rapidly as the evaporating power of the air demands its removal 

 from the leaves. The corn plant, on the other hand, is not capable of 

 supplying its large extent of leaf surface with a sufficient amount of 

 water to satisfy the evaporating power of the air, and, as a result, its 

 rate of transpiration per unit of leaf surface falls below what it would 

 be if the needed amount of water were supplied, and is thus lower than 

 that of the sorghums. 



As a farther result of the water supply in the leaves, the sorghums 

 can produce more dry matter for each unit of leaf area under severe 

 climatic conditions than the corn plant.

The Wamego Anticline. 



J. W. Beede. 



In examining the region west of Wamego an anticline fold or arch of 

 considerable dimensions was found. It lies west of Wamego and Louis- 

 ville and largely east of St. George. The outline of the apex of this 

 fold is very difficult to determine on account of the rocks being deeply 

 covered with loose glacial material, so that few rock exposures exist over 

 the territory. However, along the Kansas river this material has been 

 carried away sufficiently to reveal the surface strata. An occasional 

 exposure and the dips of the starta in the region adjoining indicate fairly 

 clearly the location of the axis, or top, of the dome. 



The total extent of the field is very great, reaching from the vicinity of 

 Manhattan on the west well toward St. Marys on the east, and a propor- 

 tional distance toward Westmoreland on the north. However, the apex 

 of the dome — the part of most importance — is fairly limited in extent. 

 This central part would serve as the reservoir of all these great collect- 

 ing grounds. The rim of this central part begins just east of St. George, 

 extending north along the west side of sections 4, 33, 28 and 21, town- 

 ships 9 and 10 south, range 9 east. From here it seems to swing east- 

 ward in a semicircular curve through section 10, the north side of sec- 

 tions 14, 13 and 18, then to the south across section 19 and the west side 

 of 20, south through 29, 32, 5, 8 and 17 to the river. 



The most important part of the fold probably is to be found in sec- 

 tions 1, 2, 11, 12, 13, 14 and the east half of 3, 10 and 15, township 10 

 south, range 10 east. The rocks of this dome have an elevation at the 

 center of nearly 300 feet above their altitude at their extreme limits of 

 the fold, thus furnishing a considerable relief and capacity for the 

 collection of gas or oil, should these products occur in the rocks below.
