Jaeger .. . ce with the desert hares; for inthose days Agassiz tortoises were plentiful allover both the Colorado and Mohave Desertsand in southern Nevada. Generally these tortoises are found on theflat plots of ground of the high rocky mesaswhere a fair abundance of succulent, growingherbs assures them of an abundant food supply, at least during the spring season. During Apriland May, when both days and nights are balmyand warm, they are out feeding at all hours.Often when traveling at night I have seen themby aid of the brilliant moonlight. As soon as thereal blistering days of summer come, not a tor-toise can be seen by day.
