INTRODUCTION. if 
Yet another incident — On the north coast of Ireland I was once 
collecting Pupe and Vertigos among the sand drift, and having for- 
gotten to bring the little tubes which I usually carried for the purpose, 
I put the shells into the bowl of my pipe and covered them carefully 
with tobacco. | On my way home I thought I could enjoy a smoke, 
and I did—till suddenly I remembered the shells and then—well, 
Tableau, as before ! 
I have often put small shells into my mouth and kept them under 
my tongue, forgotten them, smoked pipes, and found them all safe 
when I got home. I would not, however, recommend this practice, 
as some of the Hyalinze (allzaria and glabra) bite the tongue and have 
an unpleasant taste, as also do Azcylus fluviatilis and sometimes 
Limnea peregra, besides which ZL. ¢treuncatula and probably other 
species are often infested with undesirable parasites. 
LEAVES AND Moss. 
A good plan for dealing with dead leaves and moss is to take a 
quantity home, spread it out to dry and search the siftings. This 
saves much time while out, and often yields a good supply of Hyalnze, 
minute felices, Pupe, Vertigos, etc. But this should be done with 
judgment, as by taking away all the sheltering moss and the eggs of 
the animals a restricted habitat may easily be destroyed. 
SNAIL-TRAPS. 
It often happens that we come across a good shell ina likely place, 
and whenever we find a single individual we may infer that some of 
his immediate relatives are not very far distant. A large flat stone, 
log, piece of old matting, or a cabbage leaf laid over the place will 
frequently be found, after a day or two, to have some of the desired 
objects adhering to its under side. I have frequently set traps of 
this nature, which visited periodically have been very productive. 
WHERE TO COLLECT. 
No ponds or ditches should be passed by without examination, 
however barren they may appear ; and not only should the weeds be
