Thus they both made 9 visits in an hour. As regards actual 

 pace, I found thej both did about 6 feet in a minute. Soon after 

 these began, other ants came with them. It Avas a beautiful day, 

 and all my ants were unusually active. At 1 p.m. I counted 10 

 on the sticks at once, by 1.80 over 30, and at 5 in the afternoon 

 over 60. They went on working very hard, and forming a con- 

 tinuous stream till I went to bed at 11 ; and at 4 ia the morning 

 I found them still at work ; but though they were very anxious 

 and, especially at first, tried very hard to save themselves the 

 ti'ouble of going round, they did not think of jumping down, nor 

 did they throw the larvae over the edge. 



Moreover, as I had placed some sifted mould under the glass, 

 a minute's labour would have been sufficient to heap up one or 

 two particles, and thus make a little mound which would have 

 enabled them to get up and down without going round. A mound 

 1 inch high would have been sufficient ; but it did not occur to 

 them to form one. 



The followiug morning (Oct. 18)1 put out some larvic again at 

 6 A.jvi. Some of them soon came ; and the same scene continued 

 till 11.80, wlicn 1 left offobs;crviiig.
