The Main Branch," as slio\vii in Fig. 2, Avas increasing its rate 

 of growth rapidly before August 15th, and liad reached a rate of 

 over five inches a day on AugTist 10th. In both the M. B. and the 

 M. S. the rates of growth were averaged from observations taken 

 every third day, except directly after Angnst 15th and September 

 5th, when daily notes were made. On the 16th the growth rate 

 dropped to two inches; to 1.25 the 17th, remaining there until 

 the 20th. Then it rose again steadily, nntil on September 5th it 

 had attained a rate of over three inches. September Gth the rate 

 dropped to 1,75 inches, and continued to decrease until no further 

 growth was noticeable on September 11th. 



The first opposite leaves had appeared on August Gth. They 

 were on the joint rooted in pot O on August 8th. From then on 

 the M. B. had gradually beconie fasciated, until it formed a rib- 

 bon three-fourths of an inch wide. As the branch only grew eigh- 

 teen inches after leaving pot F, it was rooted at that distance in 

 pot G. The ribbon grew unequally on the two sides, curved, and 

 cracked on the longer side. Posterior to the crack, branches be- 

 gan to arise from the nearest leaf-axil in each case, and at the 

 same time (about September 9th), several other branches sprang 

 from leaves between F and G. About September 19th the broad 

 tij), by unequal gi'owth of different portions, resolved itself, with- 

 out splitting the epidermis, into several shoots, as indicated in 

 Fig. 1, and many more branches arose all over the distance F-G. 

 Some of these remained fasciated, some appeared as simple 

 branches and soon became fasciated, others have so far (October 

 25th) remained simple. Four of these branches grew much more 

 ra]>idly than the rest, and their total daily growth, which is given 

 in Fig. 2, under "Main Branch Rosette," amounted to about seven 

 and one-half inches. 



Of all the side branches which had sprung from the M. B. pre- 

 vious to August 15th, between S. B. 3 and pot C, none increased 

 in length after August 16th, and all Avhich were longer than two 

 inches soon began to turn yellow, lose leaves and diw up from the 

 tip back, while the very shortest changed only from a rich dark to 

 a lighter yellowish color. The longest are now (October 25th) 

 dried down to the two basal internodes. oSTot a single side branch 

 has fonned since Augnist 16th between pots G and F, The foliage 

 has gradually become lighter in color from the box on, until now 

 that color has reached pot F. All leaves have dropped between the
