PUBLICATION OF DATA. 



Approval has been received from the Director of the U. S. 

 Geolog-ical Survey for the substitution of the million gallon per 

 24 hours unit in place of the aibic foot per seeond unit in all 

 reports relative to Hawaiian water data. Future Hawaiian an- 

 nual reports will cover fiscal years ending June 30, instead of 

 covering calendar years as in the past. In order to make this 

 substitution, no report will be issued for the calendar year 1914, 

 but a biennial report for the period July 1, 1913, to June 30, 

 1915, will be issued. In the meanwhile, however, the past prac- 

 tice of furnishing blue print copies of data and information to 

 all interested parties will be continued.
