the outside. Roll and put one sheet in at a time, so when one 

 is to be put on the register, it will not be necessary to take all 

 of the sheets out of the tube. Keep the sheets in a dry place, 

 so that the paper will be hard while inserting the record sheet 

 in tin- cylinder. II it is desirable to keep the record sheets in 

 the gage house, the paper tube with the record sheets should be 

 kept in a two-quart fruit jar, and when taking record sheets out, 

 open and close the jar as quickly as possible. If the atmosphere 

 is damp when filling the jar with record sheets, place the jar 

 with the sheets in a hot place and when heated thoroughly, put 

 a rubber ring on the jar and screw on the cover. 



To oil the register. The clock will run two years with one 

 oiling; however, if it stands idle for one month, it will be 

 necessary to take off the hands and face and oil it with the best 

 clock oil. The bearings of the screws and of the cylinder 

 should be oiled with the above mentioned oil about four times 

 a year. A very small amount of oil should be used on the 

 screws every month. A fine wire should be used in applying 

 the oil.
