The E. wind becomes milder, the weather better, especially at 

 night, and the whirlwinds diminish. The change of seasons, whicli 

 brought so much sickness, passed away in the latter third of July. 

 In Sept., Unyarawezi is tolerably healthy. 



The normal day, at this season, is a cold high E. wind, rising 

 sliortly after the"^sun bas heated the ground, it pours from the 

 far Usagara Mountains. The sky is clear and sparkling, with a few 

 bigh cirri, and on the horizon white cumuli. Shortly after noon 

 clouds obscure the sun and confine the wind, which, however, some- 

 times blow throughout the evening and the night. The nights are 

 cool about 11 p.m., till which hour the air is still, warm, and genial. 

 It much resembles the end of an Italian summer day. The winds, 

 however, with their prodigious loads of dust, if a little less pufiy, 

 and more continuous, would rival the gales of Sind.
