we saw them emerge in large numbers out in the 
open water beyond. 
Here were the slums of a larger Grebe city than 
I had seen before, and this time I was in better con- 
dition to inspect it. ‘There were over a hundred of 
the little wet mounds close together in a compact 
area, and no knowing how many more further in 
through the grass. i did not like to push the boat 
in, as it would involve the overturning and destruc- 
tion of a great many nests, so was content with a 
somewhat superficial examination of the colony. 
The birds had been able in every case to cover their 
eggs before retreating. Pulling off the layer of wet 
debris from a number of the nearer nests, we found 
that the usual number of the eggs was three, the 
largest five. Other nests were empty, or with only 
one or two eggs. 
Then as we looked off, we saw, some distance 
away, hosts of other Grebes sitting or standing upon 
their floating nests, and realized that what we were 
inspecting was only the suburbs of the real city. 
Toward this we directed the boat. The Grebes, 
seeing us approach, slid off into the water while we 
were still at quite a distance, and in squadrons 
paddled out farther into the lake. Reaching the 
place, we found that a lane of water, “ Broadway,” 
I called it, divided the city into an east and west side. 
On the ““castcide, alone the edge of a-tract of 
grass, the nests were crowded, four or five deep, for 
some distance. A mass of them, perhaps about 
thirty, extended in a sort of neck out into the open 
water. Conditions here, as might be expected, were
