One question brought up by these measurements is whether there is any
correspondence in growth between the main axis and its branches. It
appears in these tables that there is a general correspondence, in this
tree at least. In the recitation of the class, whose tables are given
above (Nos. 1, 2, 3 and 4), we took all the measurements of these four
branches for the year 1885 and added them. We did the same for 1886, and
compared the results. The total growth for 1885 was 31-15/16 inches; for
1886, leaving out the measurement of the twig whose entire growth was in
that year, 109-3/4 inches or nearly 3-1/2 times as much. The proportion
held in a general way throughout, there being only a single case of a
branch where the growth was greater in the first year.[1] But there is a
point that must not be overlooked in this connection. The branches of the
Beech seem to grow about equally well in the first, second, third, or any
succeeding year. In some trees, as the Ash, the axillary buds make a large
growth, and the succeeding terminal buds carry on the branch much more
slowly; in other trees, as the Cherry, a branch grows very slowly in the
first few years and then suddenly takes a start. These facts would appear
in tables of growth, made from branches of these trees, but the addition
of results for any particular year would have no significance.

[Footnote 1: The spring of 1880 was a remarkably early one. Thus I find in
my diary of that year the following entries:--

April 17. The red maples are in full bloom, the elms almost over. The
leaves of the Horsechestnut are quite large. The lilacs are nearly in
leaf. April 24. We went up to Waverley and found bloodroot up, spice bush
out, violets, dog-tooths and anemones, also caltha. April 28. All the
