various stages of decay. The soil was shallow and heavy, over- 
lying chalk. All through the wood large numbers of trees were in 
bad condition, and several were dead, but the majority carried no 
large amount of Coccus. Fungi occurred on the bark in many 
cases but those noted were saprophytic species. We were told 
that the Coccus had been noticed on the estate for thirty years, but 
that it had not increased rapidly until from twelve to fifteen years 
ago. For old trees, some were quite as healthy as could be 
expected ; others were in a bad state of decay. A small amount 
of Coccus was seen on most of the trees, but, except for three 
badly-infested specimens it was in no greater quantity than may be 
ound in many plantations which show no signs of injury 
Of the three trees bearing the largest amount of Coccus, one was 
as healthy as other trees of the same age on the estate, or in woods 
or parks elsewhere. The second was in fair health, but the growth 
made in 1909 was shorter than in the previous case, while the 
third tree was in bad health, and had several dead and broken 
branches, and dead patches of bark. ere were many trees in the 
wood in a similar condition, but which bore little or no Coccus. 
On other parts of the estate a little Coccus was noticeable here and 
there. In a plantation of trees about thirty years old (near the 
Sequoia Avenue) there was a fair amount of Coccus, but it did not 
seem to be doing any serious damage ; a few trees were dead, but 
that was due to overcrowding. In this case the Coccus was not 
confined to trees of a particular character, and some of the most 
vigorous trees had as much Coccus as any. We asked that this 
plantation might be kept under observation with a view to ascer- 
taining the effect of the disease on quite young trees. 
Chenies Woods.—These occupy a portion of the Duke of Bedford’s 
Buckinghamshire estate, and they were visited on April 12th, 1910. 
Taken as a whole, the trees on this estate were remarkably healthy. 
Here and there a specimen was noted carrying a fair amount of 
Coccus, and a number of trees were seen which had broken off at 
about twenty feet above the ground. A small amount of Coccus 
was widely distributed on the trees, as elsewhere, but badly affected 
trees were few in number, isolated, and far apart. Where the 
Dead bark full of a fungus was often seen near a stump of a 
branch, the fungus being also present in the wood. Where the 
bark was dead at fifteen or twenty feet from the ground, the bark 
at the base was in good condition. In other cases dead patches of 
bark were found about the bases of the trunks and the roots, while 
the bark higher up was healthy.
