washed away by the unimpeded rush of rain water." And of an area west of the Upper Chin- 

 dwin: 'As regards cinchona prospects, the journey was disappointing. There was no need to 

 go inland from the river for all along the outer ranges the ravages of shifting cultivation were 

 only too evident. The evergreen forests are being rapidly destroyed." During the year 

 1,814 acres of taungya plantation were newly formed. Detailed tabulated data (72 pp.) is 

 appended. In rev iewing the year's work it is stated that the future before the Forest Depart- 

 ment is one of the greatest activity ; for not only has the better exploitation of the commercial 

 forests to be undertaken, but the proper conservation of all that unclassed forest on which the 

 agricultural demand is now concentrated can not be left in its present neglected condition. 

 Such vast areas as the unclassed forests of Burma (74,707,834 acres) can not long be subjected 

 to such profligate destruction as is now going on in many places for want of control and of 

 staff to exercise it. The conservation of these forests is not a matter of mere revenue, but in the 

 best interests of the whole population and most especially to the advantage of the agricultural 

 classes. — E. R. Hodson.

 wastes. Jour. Forestry 18: 31-33. 1920.— Destructive lumbering is responsible not alone for 

 the economic and financial loss due to the wasteful cutting and burning, but also for the 

 degeneration of the people through loss of the vigorous stock, poor crops, whiskey and mal- 

 nutrition. Such people need assistance from the outside and larger communities, as they are 

 not self sustaining. In such regions, a peculiar type of degeneracy is developing. — E. N.

 Adirondacks. Jour. Forestry 18: 26-30. 1920. — Costof a forester and proper forest work in a 

 lumber company was found to amount to an annual charge of 36 cents per thousand feet, 

 while the charges due to conservative lumbering amount to 65 cents per thousand. — A com- 

 ment by W. N. Sparhawk is to the effect that a number of items are not properly forestry but 

 lumbering, thereby reducing the cost considerably. — E. N. Munns.

 from the tree and the relation between the diameter of the tree at breast height and the 

 intercepted diameter on a scale held at arms length, the diameter at half the height can be 

 obtained. A formula is given for the practical application of this principle to field use. —
