PLANTING OF BAMBOO 269 
The area planted was 22,000 square meters. The time em- 
ployed in selecting cuttings was 200 hours, in clearing 207 
hours, and in planting 140 hours, making a total of 547 hours. 
Assuming labor at 10 centavos per hour, the cost of planting 
would be 25 pesos per hectare, planting being at intervals of 2 to 
3 meters. During the first four years the plantation was cleaned 
twice a year, which included the cutting back of vines and 
felling and pruning of trees. This was done at a cost of about 
10 pesos per hectare, per year, with labor at 10 centavos per 
hour. 
A second bamboo plantation was started by Dr. F. W. Fox- 
worthy at the Division of Investigation, Bureau of Forestry, at 
Los Banos, during June, 1917. This plantation covered 2 hec-. 
tares and was planted with a single species, Bambusa spinosa. 
The planting was done in the months of June and July during 
the early part of the rainy season. The ground was covered 
largely with small trees and climbing bamboos, there being 
very little grass. The climbing bamboos were cut, but the trees 
left standing. The planting was done with stump and stem 
cuttings. The stump cuttings used had roots and were about 
a third of a meter in length. They were planted either in 
a slanting position or erect. A stem cutting consisted of a 
segment with a node at either end. A slit was made in the 
internode, and then the whole segment buried in the ground, 
except that the slit was left uncovered to permit water being 
poured into the internode. In all there were planted 225 stump 
cuttings and 800 stem cuttings. 
All of the living shoots were counted and measured during 
December, 1917, and again at the end of June, 1918, when the 
plants were about a year old: The results of the measurements 
are given in Table 4. An examination of Table 4 shows that 
at the end of the year 59 per cent of the stump cuttings and 
40 per cent of the stem cuttings were alive. A comparison of 
these figures with those given in Table 3 indicates a greater per- 
centage of success in the second than in the first plantation.
