Near Sampson City, Fla., forest fires 

 have been burning for two weeks, doing- 

 great damage to farmers and turpentine 

 timber. Many buildings have been 

 threatened. 



The grist mill and cotton gin belong- 

 ing to Col. T. N. Winn, near Hinesville, 

 Ga. , were burned a few days ago as the 

 result of a forest fire. 



In this connection attention is called 

 to the article on " Forest Fires in Colo- 

 rado in 1 90 1," published elsewhere in 

 this number. The author of this article, 

 Mr. Henry Michelsen, has for years 

 been a strong advocate of forest preser- 

 vation, and each season he keeps a care- 

 ful record of all forest fires which occur 

 in Colorado. 



J- 



University of Dr. B. E. Fernow, Di- 

 California. rector of the New York 



State College of For- 

 estry, has been appointed lecturer on 

 forestry at the next summer session at 

 the Universit}' of California, to be held 

 during July and August, 1902. 



Dr. Fernow will spend three weeks 

 in the in.struction of those interested in 

 the profession of forestry, and will also 

 deliver nine illustrated evening lectures. 



J- 



Measurement There are in common 

 of Water. use two units of meas- 



urement of water when 

 used in irrigation that giving the rate 

 of flow, as of a .stream, and that .stating 

 the cubical quantity, as of water con- 

 tained in a resen^oir. 



The cubic foot per second (second- 

 foot) is the unit for the rate of flow. 

 This is a quantity of water delivered 

 by a rectangular flume one foot wide 

 and one foot deep and flowing at the 

 average rate of one foot a second. In 

 round numbers this is equal to 7^2 gal- 

 lons each second, or 450 gallons per 

 minute. 



The rate of flow is sometimes ex- 

 pressed in miner's inches, but this is 

 an indefinite quantity. In Arizona 40 

 miner's inches make a cubic foot per 

 second, and in California 50 miner's 

 inches make a cubic foot per second. 



In various localities there are interme- 

 diate values. 



The unit of capacity used in irriga- 

 tion is the acre-foot, or one acre covered 

 one foot in depth, equivalent to 43,560 

 cubic feet. One cubic foot per .second 

 flowing for twenty-four hours will cover 

 an acre 1.98 feet in depth. In round 

 numbers, a cubic foot per second for a 

 day is equivalent to two acre-feet.
