1 The arrangement of the test results on the report for gravel or sand, as reported by 

 the conference, has been altered slightly so that the report might be made on a single 

 sheet. In the case of petroleum and asphalt products and tars, the tests to be reported 

 upon were definitely recommended by the conference, but no specific recommendation 

 was made as to the order of arranging the various test results on the report form. 

 The form, as presented, has been arranged in editing.
