54 Gen. A. W. Greely-Rainfall Types of the United States. eastern Nebraska receives during these four months, April to July, inclusive, a larger amount of rainfall than the interior portions of the eastern states from Maine to Virginia; and western Nebraska receives only a slightly lesser amount. While the rain precipitation of the year diminishes to the northward and westward of Nebraska, yet the same favorable type of distribu tion prevails. The Missouri type changes by interference with the Mexican type in the southwest, the Tennessee type to the southeast, and the Saint Lawrence to the northeast. The " Tennessee" type, although not covering a very extended region, is well marked, the highest rainfalls occurring the last of winter or the first of spring, while the minimum is in mid autumn. The Tennessee type obtains over Tennessee, Arkansas, Mis sissippi, eastern Kentucky, western Georgia and, except on the immediate gulf coast, in Alabama and Louisiana. In some localities (western Kentucky and Tennessee and adjacent parts of Arkansas) the rain of February slightly exceeds that of March, the usual month of maximum, while in northern Louisiana and adjacent regions, the tendency is toward slightly greater rainfalls in April than in March. It is also to be noted that in some cases there is a tendency toward the minimum rainfall in August or September rather than October, in which month the minimum occurs for the greater portion of the area. Montgomery, Alabama; Atlanta, Georgia; Chattanooga and Memphis, Tennessee, are examples of the Tennessee type of pre cipitation.
