Perhaps one of the most attractive of our Fungi 
is the Fly Agaric (Amanita muscaria), which is like

Warty Caps is reddish-brown on the surface of its

Our walk through the wood is now ended; we 
have seen and talked about many interesting objects, 
but our attention to a few things has diverted us 
from much that we might have noticed. However, 
we have done very well, and there are other good

to talk so freely as I climb this hill, and, really, I 
think I had better not tell you too much or you will 
have mental indigestion. 
Dear me! it looks as if we are not going to get 
over the hill, for there are three subjects for us to 
consider just where we are. First, there is a colony 
of larvee of the Small Tortoiseshell butterfly feeding 
hungrily on these nettles. They are surely up 
betimes ; we do not usually get them until June. 
They are very small, so that they have not been 
long out of their shells. They will feed until they 
are too fat for their skins, when they will cast them 
off and appear in a better-fitting garb. Their skins 
will be changed a few times before they turn into 
pupe or chrysalides. After a period in the pupa
