184 The Protective Methods of certain Larve. 
hills and the sea was intersected by tidal estuaries which are 
now meadows, and the great forest of the Weald would prevent 
progress through it. Hence possibly their first settlements were 
made on the downs; the circumstances of the interments there 
all seem to indicate that they were made before the introduction 
of Christianity amongst them. 
The village church contains a Saxon arch, and also Roman 
tiles built into the walls, and it stands just outside an immense 
wall of earth, which forms a fortified camp by cutting across the 
neck of a peninsula of high ground jutting into the marshes, 
which were at one time a tidal estuary, thus making an ad- 
mirable defensive position. This camp is of Celtic origin; a 
large canoe found here some years ago is preserved at Lewes 
Castle, and another still exists under the meadows close by; the 
end of it can be seen when the adjoining ditch is cleaned out, 
but it would not be feasible to dig it up, as so doing would spoil 
the meadows. These canoes are formed out of the trunk of a 
large tree, in the method adopted by savage races at the present 
day. The space within the camp is an arable field, and although 
nothing has been turned up by the plough there, I hope at some 
time, when the crops are off the ground, to sink a trench near 
the wall to see if anything of interest can be found there. Iam 
informed that in building a cottage just outside the wall both 
bones and Roman tiles were turned up. 
It will be seen that the net result of exploring this series of 
barrows is exceedingly small, and I am sorry to have such 
meagre facts to put before you. The uncertainty as to whether 
a barrow had been opened before or not adds a decided sporting 
element to the investigations, but leads to frequent disappoint- 
ment. There were four or five, however, which had been dug 
into so roughly that it was obviously not worth while to trouble 
about them.

(Read September 17th, 1895.) 
Tue larve of Lepidoptera are remarkable for the varied 
methods they possess for their self-preservation. Those that 
are covered with hair, often of a very powerful urticating nature, 
have few, if any, enemies, excepting the ichneumon flies. Birds 
and animals give such larve a wide berth. Those larve which 
are borers, and live either in the trunks, stems, leaves, or cap-
