As it is not proper to recommend as a standard any specificpatented device, the committee recommends only, for passengerand heavy capacity freight cars, the use of side bearings em-bodying the anti-friction principle in any form that insures sim-plicity and durability to the greatest possible extent. In view of the importance of tests to be recommended later,the committee does not suggest any change in the M. C. B. stand-ard center plate. There is evidence that derailments have in many instances re-sulted from the use of side bearings carrying too great a pro-portion of the load when used with rigid underframes, and fromthe binding of improperly constructed center plates and sidebearings, which causes the wheel flanges to crowd and climb therail.

IRON which allows of their adjusting themselves to curvature anil in-equality of track is believed by the committee to be of vitalimportance, not only because there is less probability of derail-ment, but also because wheel flange wear and the danger frombroken wheels is diminished. The committee therefore calls attention to the importanceof this matter and recommends that an appropriation be madefor the purpose of conducting further tests, not only of variousforms of common center plates and side bearings, but also ofdifferent types of anti-friction center plates and side should be made for the purpose of determining the bestlocation of side bearings. MINORITY REPORT. While recognizing the desirability of fixing uniform dimen-sions for as many parts of cars as possible, I cannot agree to sub-scribe to the above report, in so far as fixing the distance fro
