136 W. & L. E. GURLEY, TROY, NEW YORK 



Portable wooden* or sheet metal houses**, 5 by 6 feet in plan, 

 have been used with success in appropriate locations. The cost 

 of such shelters is small, and they may be obtained quickly from 

 stock from their manufacturers. In arid regions, if the station 

 is to be operated only during warm weather and where rain is 

 not likely to interfere with the inspection and adjustment of the 

 register, simpler types of shelters may be used. 



When registers are to be installed at dams, provision should 

 be made in the design of the dam for a well of ample size and 

 a shelter to form part of the structure. The same provision 

 should be made when designing bridge piers or bulkheads to 

 be built in streams at points where records may be desired. 



Each shelter should be provided with a suitable register 

 table, and a saving of time will result from keeping permanently 

 in each shelter certain tools and equipment. For the small 

 adjusting levers, screw drivers, oil cans, etc., required in 

 operating the automatic register, a small box may be fastened 

 to the wall of the shelter. A couple of thin battens conveniently 

 placed will serve as a paper rack, behind which may be placed 

 stationery or wrapping paper that may be required at the 

 station. A broom will frequently be found useful, and a tin 

 pail, a shovel, an ice chisel, a stay line and lead meter weights 

 should be kept at the shelter when current meter measurements 

 are made nearby. 



CARE AND COMPUTATION OF RECORDS 



Records from Gurley Printing Water Stage Registers should 

 be wound on a tin spool furnished for that purpose, as soon as 

 they are received at the office. A No. 632 Tape Reel (See 

 Fig. 44, page 91 ) will be of material assistance in this process, 

 especially in dividing the record for computation, into days, 

 by means of pencil lines drawn across the paper strip. One 

 months record may be rolled on one spool, and the spools may 

 be filed in a filing cabinet or drawer. All information pertain- 

 ing to the gage height should be made on separate sheets, which 

 are then properly filed away for reference. The printed strip
