Messrs. Sclater and Salvin on the 
dart into a hole, or rather crack in the rock, about twenty feet 
from the ground; the noise then was louder than ever. Not 
altogether understanding this, I crossed the river and walked up 
to the foot of the cliff, and began to throw stones at the hole, to 
make the Swifts, which I had seen enter, fly out. Stones were no 
good, so I tried shouts, but with no better success. I then fired 
my gun at the hole, but still without result, the noise within con¬ 
tinuing as loud as ever all the time. My last resource was to 
climb up as far as I could, and try and poke them out with a 
bamboo-cane that happened to be lying at my feet. When I 
had climbed up a little way, what should I see but a dead 
Swift, which had fallen through the crack, and been caught on 
the ledge where I found it ? It had evidently been killed by my 
random shot. When I had descended, I fired again, this time 
frightening out five or six birds, but not, as I thought, killing 
any. As soon as these five or six got clear of the rock, they 
were pursued by all the u Cotylce serripennes of which there 
were a great number in the valley. As I was watching their 
flight, down fell a Swift at my feet. I then loaded, and was 
about to leave the spot, when a third made its appearance, falling- 
down the crack. I again climbed up to where I had found the 
first, both to see if there were any more, and to examine more 
closely. Then I found a good many feathers, some pieces of dry 
grass, and a skeleton of a Swift. This was evidently their 
common roosting-place, and there were others similar in the 
same rock ; how many inhabited the same hole I cannot say, for 
after I had shot three, and five or six were flying about, the noise 
continued as loud as ever.” (0. S.)
