If No. 1 grew in 1920, then the main shoot of No. 2 grew in 1919, from the point _o o_. It is also one foot long. Near its base are four small buds that remained dormant in 1920. There are nine branches (_d_) of various lengths besides the terminal shoot No. 1, all of which grew in 1920, for they are naturally a year younger than the main axis from which they arise; these branches are the same age as No. 1, with buds that would have produced shoots in 1921. But the terminal buds of eight of these lateral shoots (all but the lowermost) bear blossom-buds at the end; note their size and shape. Had not the branch been cut, these buds would have bloomed in 1921; the eight of them would have produced probably forty to fifty flowers; perhaps two or three good fruits would have resulted. Note that two of the lateral branches or spurs are short and weak: these would soon perish. The No. 2 branch has a dead end (_e_); in some way the terminal bud was destroyed, and No. 1 sprang from a lateral bud beneath it, changing the direction of growth. If No. 2 grew in 1919, then No. 3 grew in 1918. It also grew about one foot in length, showing that the conditions in the three years must have been very uniform. There are remains of five dormant buds at its base. There are seven side branches. As the main axis is three years old, so these lateral shoots are two years old; they are the same age as the axis No. 2. The lower one (_s_) grew less than an inch in 1919, and made a fruit-bud; in 1920 it blossomed and one fruit set as is shown by the square scar at the end; as the scar is small and the twig weak, we are safe in assuming that the apple was very small or else did not mature. A bud formed at the side of _s_ to continue the growth of the spur next year (1921), but it is a leaf-bud; apparently there was not sufficient energy to bear flowers and to make a fruit-bud; so there would have been no more fruit on this spur earlier than 1922: thus do we see that the alternate bearing of the apple-tree may have some of its origin in the fruit-spur. The side spur _f_ produced a terminal blossom-bud in 1919. In 1920 six flowers opened,--I could count the scars. One of the flowers produced a fruit, as I tell by the square scar at the end; the thickened stem also indicates fruit-bearing. The side bud in this case is a fruit-bud, but it is small and weak and is probably incapable of producing a fruit. There are no strong leaf-buds to take up the work, and this spur (_f_) would probably soon have died, as also would spur _s_. The side shoot _g_ grew to _h_ in 1919 and made a flower-bud. In 1920 this bud gave blossoms and one fruit resulted; the scar is prominent and there is an enlargement of the tissue indicating that the fruit probably attained good size; in 1920 also, two side spurs were formed each with weak blossom-buds, also a terminal shoot (beyond _h_) with leaf-bud at the end.
