THE GIRTH-INCREASE OF TREES. 71 
one Hungary Oak comes near it with 1'90; the other Hungary 
Oak, with the Wych Elm and Birch, attain fully an inch and 
three-quarters, and the Ash, at the bottom of the list, reached an 
inch and a quarter. 
III. TREES BETWEEN Two AND A HALF AND FIVE FEET 
IN GIRTH. 
Annual rate— Few of the species and none of the actual trees 
of the first or Infant Table are to be found in this category, 
which includes ten trees, three being Hungary Oaks. They head 
the list, one of them with 1°86, but it is fair to state that they are 
younger than most of the others; the Wych Elm is well up 
with 1°71; but the next best, a Turkey Oak, has only ‘57, 
and the others dwindle down to °32, the rate for ten years of a 
Horse Chestnut. 
Annual range.—This was moderate in the three Hungary 
Oaks, the Wych Elm, and Turkey Oak, the maximum being 
less than double the minimum ; but it was very great in Haw- 
thorn, Hornbeam, Lime, Sycamore, and Horse Chestnut, the 
proportion being as ‘50 to "15 in Sycamore, the best of them, and 
as ‘05 to ‘75 in Horse Chestnut, the worst ; a proof, I think, that 
these trees, healthy though they look, had passed their prime of 
growing power when only from four to five feet in girth. 
Maximum single year’s tncrease—The three specimens of 
Hungary Oak are conspicuous with 2°10, 2°05, and 1°80, andt he 
Wych Elm also mounted a trifle above two inches; but Haw- 
thorn, Lime, and Horse Chestnut do not attain more than 
about three-quarters of an inch, Turkey Oak somewhat less, 
Sycamore and Hornbeam only half an inch. 
IV. TREES FROM ABOUT SIX TO SEVEN AND A HALF FEET 
IN GIRTH. 
Sa list is now reduced to six trees, none of which appeared 
in the former categories. As they were observed for twenty 
years they may conveniently be divided into two decades. 
Annual rate—The two Beeches, which attained respectively 
nearly seven and nearly six feet in girth in the first decade, and 
seven feet and a half and six feet and a half in the second, are 
at the head, with a rate of 1:03 and ‘99 in the decade 1878-87,
