 laya, to the neighbourhood of the Jumna, forming vast forests, fre- 

 quently unmixed with any other tree, but generally confined in the 

 most northern parts within the first range of the hills, (Royle). Fl. 

 middle-sized, yellowish-white, fragrant, April and May ; fr. R. S. 

 It affords the best and most extensively used timber in India ; the 

 goodness of which must depend in a great measure on the resin, (called 

 ral in the northern, and dhoona in the southern provinces) which it 

 contains. {Royle.)

 Yields an abundance of Wood- oil. A large notch is cut into the trunk 

 of the tree, near the ground, where a fire is kept up, till the wound is 

 charred, soon after which the balsam begins to ooze out : the aver- 

 age produce of the best trees during the season, is said to be some- 

 times 40 gallons. It is found necessary, every three or four weeks, 

 to cut off the old charred places and burn them again. In large 

 healthy trees, abounding in balsam, they even cut a second notch in 

 some other part of the tree and char it as the first. These operations 

 are performed during the months of November, December, January 

 and February. Should any of the trees appear sickly the following 

 season, one or several years respite is given them. (Roxb.)
