Modern Cliff-Dwkllers

Now and then we started an Auk from its egg in 



some recess or under some projection of the rock. 



As this was the most accessible part of the cHff, 



many eggs had been gathered from these ledges, 



and there were not as many here as elsewhere, 



where they could not be reached. However, as we 



climbed down to the bottom ledge, we came up 



a line crowded

each sitting on 



its single egg laid

close in under 



the overhanging 



cliff. They afl

they saw that 



we were really 



coming down to 



them. The sud- 



denness wdth 



which they flew 



started one or two of the eggs rolling, and then 



I saw a practical illustration ot the wisdom ot the 



plan of Nature which has made the eggs of these 



birds pear-shaped. Instead ot rolling off the 



ledge, they simply turned around on their axis, 



only moving a tew inches from their place. The 



shells, too, are so hard that they can withstand a 



great deal ot rough usage, though occasionally I 



noticed one that had been broken. 



After inspecting these interesting sights, we
