We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.

GREENWICH Mean Time was adopted by the recent International Radio Telegraph Convention in Washington for use in the Convention and regulations drawn up by it. Greenwich Civil Time is used in the Navy for navigation and that time is employed in naval almanacs. The conversion table below indicates the relation between G.C.T.. G.M.T.. and 75th Meridian Time. The latter is "Eastern Standard" Time and those living in other
time belts can easily calculate the time to listen for these transmissions in their own localitv.
