Discussion at Spring convention: Some fuel determinations made on locomotives operated by the Southern Pacific systems

Cary T. Hutchinson: There are several deductions from the test data with which I am not in entire agreement. These concern the method of analyzing the data rather than the routine of the tests, of which I have no knowledge other than given in the paper. Using the data presented by the author, I am led to certain results which do not agree with his; possibly some of these can be charged to the small scale of the diagrams presented in the paper and others possibly to my failure to understand the method of presentation. It seems worth while to call attention to them, if only to bring out an explanation.
