At tin- same time, us a matter ofexperience, it is ho opinion that wheels of fair quallt]of (he weights given will afford satisfactory results. it is also recon nded that commencing September 1. 1901, wheelmakers should be required to have tip- nominal weight. PATTERN \o 2For Caks of lhv Capacity is sufficient and that no Rood will be obtained by increasingor decreasing this amount of clearance. So far as the templetfor determining these dimensions is concerned, the committeeis of the opinion that it is not practical to make the templetI locale the hub with reference to the gauge point, but thatthe practical method will be to lay a straight edge across theoutside of rim, measuring in 15/16 in., which will give the properlocation of the face of the hub. Tt. of course should be deter-mined that the pattern is so made that the wheel is 5V. all between the inside of flange and outside of rim, beforethe measurements n ferred to above are taken.

It is the opinion of the committee, based on actualexperience, that any thickness greater than 1 in is .sufficientan
