The date of one visit was not recorded, and no temperatures 

 were taken. On this occasion heavy rain was falhng ; the mound 

 was opened right out, and water was running into the egg-chamber. 

 Where it is stated that the birds were " at wheat," they were 

 seen at a farm a considerable distance from the mound. 



The respective times when the readings of the thermometer 

 were made at the camp and at the mound were all recorded, but 

 to economize space I have not included these details. One visit 

 at the mound was as early as 4.5 a.m., and another as late as 

 8.15 p.m. ; but generally the inspections were much nearer 

 mid-day. It is remarkable how even the temperature remained 

 in the mound for long periods, although it varied so much at the 

 camp. 



The mound measured 64 feet in circumference (an unusually 

 big specimen), was about 2 feet high when flattened out, and 

 3 feet 8 inches at the highest point when heaped up. The egg- 

 chamber was scooped into the ground about i foot (diagram i), 

 and its circumference was inclined towards an oval with a 

 diameter from 2 feet to 2 feet 3 inches (diagram 2). 



The first five eggs were placed as indicated in diagram 3, and 

 after the fifth egg had been deposited all subsequent eggs were 

 placed in like rotation, so that at any time after the seventh egg 

 had been taken Mr. Scarce knew in which part of the egg-chamber 

 to look for the next egg. Add 5 or a multiple of 5 to any of the 

 figures in diagram 3, and the egg bearing the resulting number 



20
