,•!',. tbe Kdilof., s ir \',.w that the conference of evil eti-ineer- is in se .ion at Auckland, it ma. not ;,e .i.l of I'hiee to place befor.' them the method of mixing concrete i'.ir road work, etc At the present time all concrete for road- . mixed h.v" machines, which, to my mind, is not satisfactory. I defy anyone to get a uniform mix with ani machine that i- working nt present, and the waste of cement that is required lo make a decent mixture i- a very big item. l'"or instance, with machines the aggregate is about -H to 1. With hand mixing i would guarantee I hat a hotter ami more uniform concrete ..hi 1.1 lie turned out at il to I. Tims tiie saving of cement would e.isilv balance ihe cost of hand-mixing. I would like, when the members of the conference are vi-iting tiie roads in course of construction that they may see for themselves tiie worth uf my contention.—-J am. etc., ' A PRACTICAL MAN.
