In 1906, he leased more than of prairie land in the Athi Plains region of British East Africa, southwest of present-day Nairobi. There he founded an ostrich-ranch and hunted the game which was at that time plentiful on Kenya's high plateaus. The Pease property, Kitanga near Machakos was situated close to the Uganda Railway, and this enabled Sir Alfred to host a number of the famous travellers who hunted during the great age of safaris. As a result, he is mentioned in many of the personal accounts of the period.
