Where rabbits abound seedlings and coppice are destroyed. To 
fence with wire netting would swallow up the profits. 
He does not consider that we need give up game but that 
rabbits must be exterminated. 
The planting of trees, in considerable numbers would no doubt 
add to our water supplies—a matter of increasing importance. 
From the foregoing I have formed the following conclusions :— 
1. That the Elm is found in submarine forests and in pre- 
historic formations. 
2. That it did not exist in recent times in this part of the 
country. 
3. That it was introduced here by the Romans, and spread so: 
rapidly, that it was in use as timber during Saxon times. 
4. That after driving out the fir and other trees, its period of 
decline has now come, and it is far from impossible that 
it may in its turn be superseded by trees of the fir tribe. 
Before turning to the second part of my paper, I will say a few 
words about the Elm bark beetle (Scolytus destructor) which some 
people suppose, as I think mistakenly, to have lately killed four or 
five fine Elms in the Park near the Miller Vase. 
Col. Blathwayt informs me that this beetle is only successful in 
its attack on injured or diseased trees. 
That great authority, the late Miss Ormerod, in her account of 
this beetle has the following remarks :— ‘ 
“The circumstance of Scolytus attack, and sickly growth of 
the tree or decay of the bark occurring together, has given rise 
to much discussion as to whether the Scolytus attack caused the 
decay, or weakened health induced attack.” 
“Tt is observed by Dr. Chapman, from whom I take much of 
the abovelife-history (see “Entomologists’ Monthly Magazine,” 1869, 
pp. 126, 127), that healthy growing trees are supposed to repel 
the attacks of this genus of beetles by pouring sap into their 
burrows.” 
“He notes that in the case of the Scolytus pruni he had
