My comrade and I separated for a little, losing sight of each other among the sand-hills, and when we came together again he reported that he had seen the sparrow. He had happened upon it unobserved, and had been favored with excellent opportunities for scrutinizing it carefully through a glass at short range; and being familiar with its appearance through a study of cabinet specimens, he had no doubt whatever of its identity. This was within five minutes of our arrival, and naturally we anticipated no difficulty in finding others; but for two or three hours we followed the chase in vain. Twice, to be sure, a sparrow of some sort flew up in front of us, but in both cases it got away without our obtaining so much as a peep at it. Up and down the beach we went, exploring the basins and sliding down the smooth, steep hills. Every step was interesting, but it began to look as if I must go home without seeing _Ammodramus princeps_. But patience was destined to have its reward, and just as we were traversing the upper part of the beach for the last time, I caught a glimpse of a bird skulking in the grass before us. He had seen us first, and was already on the move, ducking behind the scattered tufts of beach-grass, crouching and running by turns; but we got satisfactory observations, nevertheless, and he proved to be, like the other, an Ipswich sparrow. He did not rise, but finally made off through the grass without uttering a sound. Then we examined his footprints, and found them to be, so far as could be made out, the same as we had been noticing all about among the hills. Meanwhile, our perambulations had not been in vain. Flocks of snow buntings were seen here and there, and we spent a long time in watching a trio of horned larks. These were feeding amid some stranded rubbish, and apparently felt not the slightest suspicion of the two men who stood fifteen or twenty feet off, eying their motions. It was too bad they could not hear our complimentary remarks about their costumes, so tastefully trimmed with black and yellow. Our loudest exclamations, however, were called forth by a dense flock of sea-gulls at the distant end of the beach. How many hundreds there were I should not dare to guess, but when they rose in a body their white wings really filled the air, and with the bright sunlight upon them they made, for a landsman, a spectacle to be remembered.
