delivered, the cost of cutting this, $1.25, of hauHng, 75 cents, leaves $2- 

 per cord stumpage and margin, and, since the woodlot is growing at 

 the rate of six 16-inch cords, the net returns per acre are $12. Instead 

 of now relating the income represented by increment to the value of 

 the growing stock of 26 standard cords, which would make the interest 

 rate something like i^ per cent, the author assumes a value of $200, 

 giving 6 per cent interest. 



The 55-acre sugar bush woodlot, on which about 550 trees are tapped, 

 making 160 gallons of syrup at $2, or less than $6, per acre gross, since 

 the cost was $195.75, leaves a net profit of only $2.26 (23 cents per 

 tree). It is stated, however, that this is not an "ideal sugar bush." In 

 addition, wood resulting from thinnings, one 16-inch cord per acre, nets 

 an additional $2, so that if 6 per cent is demanded the value of the lot 

 would figure $71 per acre, or only about one-third of the fuel lot. No 

 data are given to ascertain the actual value of the growing stock of the 

 sugar bush. 



The cost of sugaring is given as follows : 



Tapping $10.38 



Gathering sap 69 . 80 



Boiling sap 31-42 



Taking up buckets 4-75 



Wood 35.40 



Containers 24.00 



Depreciation on plant 20. 00 



Total $195-75

Last year's field planting at the Fort Valley Experiment Station, 

 which, due largely to the favorable spring and foresummer, made a 

 very good start, suffered severely from drought during the fall and 

 early winter. The summer rains were unusually light, being practically 

 over by August 5, while normally they continue throughout August. 

 October, November, and December yielded only a trace of precipita- 

 tion, while normally the total for this period is between 3 and 4 inches. 

 Large numbers of plants which made a vigorous growth in July were 

 dead or dying by January i. By November 13 the percentage of sur- 

 vival had fallen from 90 to 73. No count has been made this spring, 

 but the percentage is probably not above 50. In this connection it is
