LOCK : THE GROWTH OF GIANT BAMBOOS. 
DESCRIPTION OF PLATES. 
Plate XXI., fig. 3. The curves represent by vertical lengths the 
hourly growth of culms Nos. 1 and 2 (Table XIII., p. 239) recorded in 
mm. on June 22 and 23. At the beginning and end of the curve 
records were taken at 2-hour intervals and the average hourly growth 
is given. 
Scale : 2 mm. in the fig. represents 1 mm. actual growth. 
Plate XXI. , fig. 4. Hourly growth of Nos. 1 and 2 on June 29 and 
30 (Table XIV., p. 24) scale the same as in fig. 3. 
Plate XXII., fig. 5. Hourly growth of culms Nos. 5 and 6 on June 
29 and 30 (Table XIV., p. 24). On June 30 from 5.30 a.m. onwards. 
No. 5 was covered with an opaque cylinder which was removed hourly 
for about 30 seconds whilst the growth was recorded. No. 6 remained 
uncovered. 
Scale: 3 mm. in the fig. represents 1 mm. actual growth. 
Plate XXII., fig. 2. The four upper curves represent the daily 
growth from July 21 to August 10 of— 
No. 1, Dendrocalamus, see Table IV., p. 227. 
No. 4, Dendrocalamus, see Table IV., p. 227. 
No. 11, Gigantochloa see Table VI., p. 232. 
No. 12, Dendrocalamus, see Table VI., p. 232. 
Scale: 1 mm. in the figure represents 4 mm. actual growth. The 
lower curve represents the daily rainfall. Scale X , 
Plate XXIII., fig. 1. The upper curve represents the daily growth 
of Culm No. 1 and the dotted curve that of No. 2. The lower curve 
represents the daily rainfall from June 14 to August 16. The 
broken line in each case represents the average growth (or rainfall) 
for consecutive periods of three days. Scale, daily growth : a height 
of 1 mm. = 5 mm. growth. Three-day : 1 mm. = 15 mm. growth. 
Rainfall, daily and Three-day : 1 mm. = 1 mm. rainfall. 
Plate XXIII., fig. 6. The curve g. represents the ^hourly growth 
of culm No. 9 on August 17, 18, and 19 (Table XVI., p. 245). The 
average rate of growth for each hour is here more correctly represented 
by the vertical height above the base line of a horizontal, the length of 
which represents 1 hour. The curve p.s. represents changes in the 
percentage moisture of the air; t, represents temperatures. 
Scale : 2mm. = 1 mm.growth. Psychrometer : 1 mm. =1 percent. 
Temperature : 1 mm. = 0*5°C.
