UNION OIL COMPANY OF CALIFORNIA’S TANK STEAMER LA BREA. 205 
As the author is not present, and no one desires to discuss the paper, we will extend our 
thanks to Mr. Frear for the presentation of the paper, and pass to the next and final paper 
on our program, No. 17, entitled “The Commercial Gyroscopic Compass,” by Mr. Elmer A. 
Sperry. 
Mr. Ermer A. Sperry, Member:—Mr. Chairman and gentlemen, I do not think I need 
to take very much of your time. In speaking to our president, Mr. Taylor, about the paper, 
he suggested that I should take the time available for the presentation of the paper to tell you 
what makes a gyro-compass point north, and as it will only take two or three niinutes to do 
that, I will proceed.
