KANSAS, popularly known as the "Sunflower State," is the central commonwealth of the United States, lying between 37° and 40° N. and 38' and 102° I' 34" W. It is bounded on the north by Nebraska, on the east by Missouri, on the south by Oklahoma, and on the west by Colorado. The State is nearly rectangular in shape, with a breadth of about 2 i om. from north to south and a length of about 41 om. from east to west ; the total area is 82,158 sq.m., 384 of which are water surface.
south-west, below the Arkansas river, is an area of sand-hills, and the Ozark plateau region, as above stated, extends into the south east corner, though not there much elevated. The great central valley is traversed by the Kansas (or Kaw) river, which, inclusive of the Smoky Hill branch, extends the entire length of the State, with lateral valleys on the north. Another broad valley is formed in the south half of the State by the Arkansas river, with lateral valleys on the north and south. The south-east portion contains the Neosho and smaller valleys. In the extreme south-west is the valley of the Cimarron, and along the south boundary is a net work of the south tributaries of the Arkansas. Numerous small affluents of the Missouri enrich and diversify the north-east guar ter. The streams of Kansas are usually fed by perennial springs, and, as a rule, the east and middle portions of the State are well watered. Most of the streams maintain a good flow of water in the driest seasons, and in case of heavy rains many of them "un derflow" the adjacent bottom lands, saturating the permeable substratum of the country with the surplus water, which in time drains out and feeds the subsiding streams. This feature is par ticularly true of the Saline, Solomon and Smoky Hill rivers. The west part is more elevated and water is less abundant.

The soil of the upland prairies is generally a deep rich clay loam of a dark colour. The bottom lands near the streams are a black, sandy loam; and the intermediate lands, or "second bot toms," are a rich and deep black loam, containing little sand. These soils are very easily cultivated, free from stones, and ex ceedingly productive. There are exceptional spots on the upland prairies composed of stiff clay not as easily cultivated, but highly productive when properly managed and enriched. The south west section is distinctively sandy.
