THE MARINE AQUARIUM. 67 
searching the tide-pools and the boulders at low-water 
mark, masses of rock will be found covered with weeds of 
various forms and colours. Select the green grassy kinds, 
and chip off each with a portion of rock attached, for a 
sea-weed has no root, and if detached from its rocky site 
inevitably perishes. 
Any one using a little perseverance and judgment may 
secure, at any part of the coast, sufficient good specimens 
to stock a tank of moderate size; and if the collection be 
watched closely for a week or two, the unsuitable sorts 
will make themselves known by their increasing shabbi- 
ness, and must either be removed altogether or treated 
according to the instructions to be included under the 
head of management in a subsequent chapter. 
A few anemones may be detached from the rocky | 
hollows in which they have ensconced themselves. The 
common smooth anemone, which may be known in a 
moment by its near resemblance to a large deep coloured 
strawberry, should be secured in plentiful numbers, for it 
is equal to most of its kindred in beauty, and is so hardy 
as to submit to the harshest treatment unhurt; the more 
delicate kinds of anemones, especially the white ones, | 
should be obtained in the same way as the weeds; 
namely, detached with a portion of the rock on which 
they are found adhering. 
In packing the collection for carriage, care must be 
taken not to allow any pieces of rock to press upon the 
soft anemones. The whole may be brought away in jars 
of sea-water, or packed in masses of wet fuci gathered 
from the beach.
