granting the administration authority to cut tariff rates by 50 per cent from

tained the tariff-cutting provision was

“an essential weapon to preserve the American free enterprise system.” Sen.

Joseph O ’Mahoney (Dem., Wyo.) viewed the delegation of power “a grave threat to democracy.”

On the Republican side, Sen. Robert T aft of Ohio claimed further tariff re­

duction would “cripple American in­

dustry,” while Sen. Charles W . Tobey of New Ilam shire chided his fellow Re­

publicans with the observation, “the Republican party hasn’t learned much.”

Testimony of industry witnesses be­

fore the Senate Finance Committee brought out divergent views of the

trade agreements program, its benefits and its danger.

II. L. Coe, representing the Bicycle In ­ stitute of America, told the committee how

American manufacturers through a pro­

motion campaign costing several hundred thousand dollars had revived interest in started developing models which would com pete with those for which our do­

mestic manufacturers had created a sub­

stantial demand, and were prepared in

facturers had to discontinue entirely pro­

It is obvious that so far as bicycles are concerned there was no ‘reciprocity’ in this deal, and that we are the victims of some astute maneuvering on the part of our cousins across the Atlantic.

Endangers Employm ent Program

“It is because of this experience that we urge this committee to prevent con­

tinuation of a procedure which surely will take from thousands of American work­

men the opportunity to earn a living in their chosen occupation. Every foreign- built bicycle w hich comes into the Amer­

ican market means one of our workmen being idle for a day and a half. At a time when American industry will be called on for almost superhuman perform­

ance in meeting the unemployment situa­

tion, this is bound to have a serious effect.

“Certainly,” Mr. Coe added, “until Great Britain has shown an inclination and put into operation regulations modi­

fying the ‘sterling bloc,’ the Dominion preference, and other advantages, the benefits of which are denied to American manufacturers, it is no tim e to authorize , still further reductions in tariffs in the hope that other countries will do likewise.
