May 22d. 1879. on Silver fir (A. pectinata?) at Leith Hill Pl.

Many branches enlarged into huge solid oval knobs, with very rugged bark. These when young often or generally produce shoots, which rise vertically up, but when they produce secondary branches, these are horizontal & normal.

The leaves on all these branches are produced precociously.

Shoots seem first to project obliquely & subsequently they fresh ones grow vertically & these produced horizontal shoots— [sketch]

Wood quite solid — in one knob 24 rings & bark very thick

[225v]

Most of the branches grow out horizontally, but some seem to have lost all sense of direction & after growing Centrifugally bow round to centre of stem of tree— Some grow vertically & so through time cannot doubt guided by apogeotropism.—
