“At noon I counted the incoming stream storming in from southward — 
this side seeming to be the main line of travel to the fishing grounds. They 
came in groups of all sizes up to twenty-five and thirty. The stream 
averaged almost exactly one hundred birds a minute. In eight counts the 
highest number a minute was one hundred and twenty and the lowest was 
sixty-nine, but the average was a hundred. This means that six thousand 
birds an hour were streaming homeward. ,, 
Each day a few puffins were seen that were unable to rise, but flapped 
and splashed and bumped over the waves, using legs and wings to their 
limit. In such manner the birds could almost equal the speed of the ship, 
9 knots. The only explanation for this inability to fly seemed to be that 
they were too heavily laden with food. 
Three or four times at long intervals, between the southern Kurils and 
Unalaska, scattered individuals, or twos and threes at most, of what sup- 
posedly were the young of the previous year, were encountered. Only one 
of these was seen in flight. These birds lacked the white face and yellow 
plumes, and the bill, though mainly red, lacked the high, curving culmen 
of the adults. It was not plain why there were so few of these immatures.

All in full summer plumage. 
Fratercula corniculata (Naumann). Horned Puffin 
Seen only eight times on the return trip, in comparatively small num- 
bers. On August 1 a dozen appeared off cape Shipunski, Kamchatka, and 
on August 3 as many were seen flying up to a cliff above the shore near 
Nikolski, Bering island, where probably they were nesting. A small 
breeding colony was reported by Mr. D. A. Stevenson near Unalaska 
village, but heavy weather prevented a visit. 
When both puffin species were seen together, the Horned appeared 
less grotesque, smaller, and more active than the Tufted, and flew with 
less droop to the rear end of the body. The Tufted always flies with his 
head higher than his tail. 
Cerorhinca monocerata (Pallas). Rhinoceros Auklet 
Observed only in Japan and on the British Columbia coast on the 
return voyage. On July 1 a partial skin of an adult in breeding plumage 
with the head still in the flesh was found on the stones of the waterfront, 
Hakodate harbour. Later, more skins were found floating in the bay 
among the shipping. A single bird was observed in harbour on July 7. 
Between Hakodate and Amori, July 8, some small flocks were seen, this 
being almost the only w T ater-bird encountered. At Amori the underwater 
period of two working near the ship was found to be from 1| seconds to If 
seconds. Just before diving, they opened their beaks and invariably 
spread the wings. 
On August 18 about two hundred Rhinoceros Auklets were seen 
between Malcolm island and Vancouver island, mainly in small flocks, 
heading southward on the wing as though in migration. 
Phaleris psittacula (Pallas). Paroquet Auklet 
On July 13, at Broughton bay, in the Kurils, three auklets seen near 
the ship were taken to be of this Bpecies. This was based mainly on the
