feet above the earth j the funiiel-shapeJ fonnatioii must have 

 been composed of tons o£ thousands of Storks, all circling 

 round and gradually rising higher and higher. As I got 

 nearer I made out several more of these formations, one 

 evidently not being large enough to accommodate them all. 

 After they had remained in the air for some time they 

 gradually floated down to the earth again and settled amongst 

 the scattered trees on the slope, up which I was driving, 

 some distance from the road, and I was able to get a good 

 view of them. When I had driven some distance beyond 

 them they rose again in the same funnel-shaped formations, 

 and were still <xvratino; when last I saw them throui>h the 

 heavy iiaze. The haze was due to the intense heat, the time 

 being about midday. I did not see any AVhite-l)elIied Storks 

 on the way back, and as I was travelling by a different 

 road, do not know whether they had left the place where I 

 had seen them a fortnight before. On my return to Pretoria 

 I paid a special visit to some lucerne-fields at Wonderboom 

 and Onderstepoort, where they were nearly always to be 

 seen during the summer months, as I wished to see whether 

 they had left or not. Not a single specimen was to be seen ; 

 but about a week later I noticed three at Elofsdal, which 

 seemed to be immature, their legs being covered with a 

 white chalky substance. The probable reason for this early 

 migration was the dryness of the season and the cold winds 

 which had been Ijlowing during January and February
