CRUSTACEANS 
The abundance and variety of the marine crustacea recorded from 
the waters of Lancashire to the south, from the Isle of Man on the west 
and from the Firth of Clyde to the north of this county are an ample 
guarantee that Cumberland itself is richly supplied with a similar fauna. 
Many crustaceans are rapid and powerful swimmers. Some walk and 
run with great agility. Those that can only tardily creep and crawl often 
have a tortoise-like perseverance. Many are carried along by currents. 
Many attach themselves more or less permanently to divers kinds of moving 
objects. Almost all or not improbably all are so extremely prolific that 
the wide dispersal of their offspring is an obvious necessity of existence, and 
is well provided for in the restless waters they inhabit. It follows that no 
county can plume itself except quite accidentally on the possession of 
species denied to its immediate neighbours. Occasionally an erratic may 
be brought by a warm current or a cold current from some alien climate, 
or may come from far distant waters entangled among the incrustations 
on the sides of an ocean-going vessel. Such strangers, if they can main- 
tain their ground, will soon spread from the port of entry to adjacent 
points of vantage. The neglect then which has befallen this branch of 
the marine fauna of Cumberland must not in any way be attributed to 
dearth of materials. All that can be fairly inferred is that the coast line 
by its bold protrusion westward has proved unattractive to collectors. The 
naturalist usually prefers to work in tranquil bays and the retired nooks 
of winding inlets, leaving the treasures of exposed waters to such adven- 
turers as Horace describes with ribs of oak and triple bronze. 
In regard to the inland crustaceans of the county there is much 
interesting information available. Unfortunately for the terrestrial iso- 
poda or woodlice I have only been able to find a single notice. This 
however testifies to their occurrence and to a singular community of 
taste between them and several other kinds of Arthropoda. In a paper 
entitled ‘Reminiscences in the Study of Natural History’ Mr. Tom 
Duckworth describes the process of sugaring trees with rum and treacle 
for entomological purposes just before dark and waiting till the moths 
began to fly, after which, he continues, ‘if it were a good night, we 
were pretty busy for some time boxing the insects; then came a lull, 
and after a little rest other species came to our sweet compound. I 
don’t know what teetotalers may think, but I have seen centipedes, 
woodlice, earwigs, beetles, spiders, and slugs all attracted to the mix- 
ture. I have seen them with their eyes shining like little globes of fire
