A SEABIRDS’ ROCK.

The entire resources of the establishment are called into service, 
and deficiencies in accommodation, and entire absence of the 
luxuries, and occasionally of not a few of the necessities, of life, 
are only subjects for merriment and good-natured chaff. 
On the following morning the “ Hyaena” steamed down the 
Menai Straits, dredging and tow-netting as she went, Carnarvon 
Bay being reached early in the afternoon. The party then 
slowly worked their way up the southern coast of Anglesea, 
anchoring for the night in a sequestered bay known as Porth 
Dafarth. There, after nightfall, some interesting experiments, 
tried with great success on a previous occasion, were again 
made, viz., tow-netting by electric light. A large arc-lamp was 
hoisted to the mast-head, and tow-nets, each with a small 
electric light within, were lowered to the bottom. Hosts of the 
smaller marine Crustacea were thus captured, and it was possible to 
pull up by hand-net abundant specimens of Amphipoda, Cumacea, 
and Schizopoda, which were to be seen darting about in the bright 
path of the electric ray. So enthusiastic were some of those on 
board that they got up at three a.m., and tow-netted along the 
surface of the water, with the object of determining whether the 
animals then to be found were different from those captured by 
daylight. Their energy was rewarded by securing a plentiful 
haul of Copepoda in great variety. 
The next day was spent in dredging and tow-netting along 
the coast, the prizes being several rare sponges and ascidians, 
along with abundance of Comatula, Holothurians, Nudibranchs, 
Zoophytes and Polyzoa. On returning to Porth Dafarth the 
electric experiments of the previous evening were repeated with 
success. 
Monday morning brought with it the disagreeable knowledge 
that the holiday was at an end, and that there only remained the 
journey back to soot and civilization. Such regrets, however, 
were to a great extent tempered by the consciousness of success 
following on hard and healthy labour, and the knowledge not 
only that we were carrying home with us in the numerous col- 
lecting-jars in all probability many additions to the fauna and 
flora of the district, but that our three days’ holiday on the sea 
had given each one of us a fresh stock of health and vigour 
wherewith to meet the less enjoyable, perhaps, but necessary 
labours and duties of city life. R. J. Harvey Gibson. 
A SEABIRDS’ ROCK AND ITS BRUTAL VISITORS. 
E have more than once had occasion to mention the 
good work done by the Daily Graphic for the Selbornian 
cause. There could be no better example of this than 
the admirable article in that journal for May 31, on 
“ A Visit to a Seabirds’ Rock.” The rock in question is the 
island of Grasholm, off Milford Haven, which the writer of the 
article describes as a spot of the greatest interest to ornithologists, 
its winged inhabitants including puffins, guillemots, kittiwakes,
