ean THE ROSEATE TERN. 
enchanted isle of wondrous beauty. As the barque of the gentle pirates grated 
on the strand, a thousand Purple Martins rose in a cloud from a dead hack- 
berry tree and whirled about in wild confusion until better counsels prevailed 
and they returned to slumber. 
Not so the Terns. Nothing could completely lull their fears; altho, when 
we made our bivouac in the woods, the mothers did settle to their eggs. The 
Terns were everywhere. We found them nesting indifferently upon the pol- 
ished limestone of the western shore, the naked gravels of the south end, the 
grassy paddocks of the upland, or within the dim and grassless shade of the 
interior. The Terns owned the island and their clamor was really unceasing. 
A few were crying all night long, and the noise at four o’clock in the morning 
was nothing short of an uproar. We estimated that something like fifteen 
hundred Terns found harbor upon the island, but we did not attempt a nest- 
and-egg census. 
Lest some suspicion enter the mind of the reader that we too were bent on 
plunder, let me hasten to confess that we helped ourselves freely to addled eggs 
and secured two fresh sets for the museum of Oberlin College. No firearms 
were discharged during the entire trip. If others will practice similar modera- 
tion, we bid them Godspeed. 
Arrived again at Isle St. George, on the evening of the 8th, in time for 
camp, the Terns still followed us, in spirit if not in body. Altho we had put 
six watery miles between ourselves and the nearest Terns, on several occasions 
this evening and the following morning, I heard them screaming. I say heard, 
not vividly recalled alone, for the impression made by their outcries upon the 
subliminal mind was so intense that it reproduced the full chorus, by means of 
an auditive hallucination, which lasted several seconds at a time. For an ama- 
teur psychologist it was an interesting experience, in no wise diminished, ap- 
parently, by the fact that the normal consciousness became instantly aware of 
the trick that was being played upon it, and alert to observe the process.
