Abstract :
A report is now in circulation on Proposed American Recommended Practise on Line Work dealing particularly with “Methods of Indicating Bolt Heads, Nuts and Screw Threads.” This report is the result of the work of a subcommittee of a Sectional Committee working under the Rules of Procedure of the American Standards Association and joint sponsorship of the American Society of Mechanical Engineers and the Society for the Promotion of Engineering Education. The committee solicits criticisms and suggestions from those interested in drafting room practise. Copies of the report may be obtained from the chairman of the subcommittee, S. Ketcham, 140 Cedar St., New York, N. Y. to whom all communications should also be sent.
