336 SCIENTIFIC NOTES. 



burgh, the average growth of one specimen was six inches a day in a 

 temperature of from 65° to 70°. The Burmah Bamboo (Bambusa gigan- 

 tea) is considered the prince of Bamboos. It attains the height of 100 

 feet, each joint ranging from 20 to 24 inches in length, and as much as 

 36 inches in circumference. It has been known to grow 18 inches in 24 

 hours. This bamboo in Bengal attains a height of 65 feet. Of indige- 

 nous kinds the Bambusa Tulda rises to its full height of 70 feet in about 

 one month. This is at the rate of about an inch an hour and should be 

 visible. The " Balcoo Bans," chiefly used in house building on account 

 of its toughness and solidity, averages from 50 to 60 feet in height. 

 The " Tulda Bans" was used some seven years ago in a novel way by 

 some Burmese villagers as a means of defence. By taking three joints, 

 then cutting one to make a mouth, scooping out the centre joint, and 

 boring a hole in the third, and then loading it with powder and shot, 

 they managed to keep off the intruders. These imitation guns would 

 often stand out five or six shots when well wrapped up with jute fibre, 

 or any other strong description of rope. In the absence of this protec- 

 tive covering, they would often burst in the second discharge.
