The pen will pass once across the sheet for each one-half inch of precipitation, and the sheet is subdivided to represent hundredths of inches of precipitation. The cylinder is 12 inches in circumfer ence and revolves twice in twenty-four hours. The sheet is subdivi ded into ten-minute spaces, and intervals of one minute of time can be determined.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
