length. A Scotch Fir, with a girth of 7 ft. 5 in. at 5 ft., has a 
fine clean bole of 40 to 45 ft. A Gean tree has a circumference 
-of 7 ft. 64 in. at 3 ft. 6 in., an apparent increase of 14 in., but, as 
the stem is much twisted, it is difficult to make a satisfactory 
comparison with former measurement. In the little plantation 
already mentioned is a remarkable example of two trees, an Ash 
and a Sycamore, united at the base. Were they of the same species, 
it might be argued that it was one tree dividing into two about a 
couple of feet from the ground. On one side the line of division 
can be traced down for a foot or so, but on the other it is dis- 
tinguishable for a few inches only. 
Many of the Sycamores are being slowly killed by insects. 
Other trees are also attacked, but none so much as this species, nor 
do the trees in other parts of the district seem so badly affected as 
those on this estate. The flower-shoots of a Horse-chestnut tree 
were lying plentifully on the ground, and, on examination, it was 
seen that the peduncle had been eaten through at the base by an 
insect. None of the trees were in bloom. The following mosses 
were observed :—Barbula levipila, Brid., Zygodon viridissimus, 
- Dicks, Hypnum elodes, Spruce.
