Then, I remember sometwenty years ago the Plymouth CordageCompany desired to install an engine forhauling heavy stuff through their yard. Each method of producing or trans-mitting power, whether by steam, or gas,or oil, or electricity, or compressed air,has advantages of its own under favoringconditions, but the use and value of com-pressed air seems heretofore to have beenbut partially known and poorly appreci-ated. I quote from Richards : The useof compressed air has been slow of de-velopment, and is still backward, but atthis writing I am able to enumerate twohundred distinct and established uses ofcompressed air, and in more than ninety.

There was thendevised an air locomotive and we sent thedesigns to the Boston Locomotive Works,who built it without giving any guarantythat it would be efficient, but that little airengine is operating to-day, carryingaround the heavy stock in the yard. WhenI returned from Liverpool I reported tothe Cotton Manufacturers Associationthat the English were a generation aheadof us in this country, but we appear tobe catching up with them now in the useof air pressure. per cent, of those uses electricity is abso-lutely inapplicable, and in the remainder,which form a field more or less open toother agencies besides either air or elec-tricity, the air generally has the advan-tage. In the Norwich plant the production ofcompressed air is very uniform and thepressure is held steadily at about ninetypounds while the compressor is in opera-tion. A card from the pressure recordinggage shows that the pressure for thewhole twenty-
