Abstract
Kenya Colony offers a rich field for the study of ticks and tick-borne diseases. The natural conditions under which both ticks and the diseases exist range from those of the hot, low-lying coastal lands to the equable climate of the highlands culminating in the colder upland country and mountain slopes. The variety of conditions is also attributable to the extensive tracts of bush-covered country, the high plateaux with their scanty growth of vegetation, and to the forest-clad ridges and mountains.
