SWIFT.— AT.PINE SWIFT. 163 



these birds flying to and fro under a bridge, only a few 

 inches above the level of the surrounding fields, and, as the 

 water was low, I managed to get under it, and there found, 

 on the piece of timber supporting one end of the planks of 

 the bridge, a nest containing two eggs. On another occasion, 

 I found several birds sitting on their nests on the wall-plate 

 under the eaves of a church, and took them off to see liow 

 many eggs they had, placing the old birds by the side of the 

 nest, when they made no effort to move, and I put them back

 great numbers of a species of Hippobosca. It leaves us 

 early in August, but I have once seen it as late as the 14th 

 of September.

 about the Cathedral in Berne, whither I went for the pur- 

 pose, and well was I rewarded ! for it was a beautiful day, 

 and I saw great numbers of this magnificent Swift careering 

 around, and far above, the sjiire. I was not so successful, 

 however, in procuring the egg, in hope of which I ascended 

 the interior of the spire, for the only nest I found, but did 

 not see, was in a hole which I thought I could reach from 

 a small opening at the highest accessible point. By leaning 

 out as far as possible, I could just touch an egg with the tips 

 of my fingers, but durst not reacli out an inch further, the
