More complete data of Addi Ugri, an Italian sanatorium on one of these Erythrean hill-stations, are extracted below from a pamphlet by Captain Tancredi, an Engineer officer. The hottest time of the year is, it will be noticed, in the spring, and the rainy season takes place at the normal time in July and August, after the setting in of the south-west monsoon. There is also a secondary period of rainfall about February and March, corresponding to our “chota bursat” in India.
