B. Cars, Ottawa, 111.
258 43. The quantity of material to be mixed at one time depends on the number of test pieces to be made; 1, 000 grams is a convenient quan- tity to mix by hand methods.
44. The Committee has investigated the various mechanical mix- ing machines thus far devised, but cannot recommend any of them, for the following reasons: (i) the tendency of most cement is to "ball up" in the machine, thereby preventing working it into a homo- geneous paste; (2) there are no means of asce...rtaining when the mix- ing is complete without stopping the machine; and (3) it is difficult to keep the machine clean.
45. Method. The material is weighed, placed on a non-absorbent surface (preferably plate glass), thoroughly mixed dry if sand be used, and a crater formed in the center, into which the proper per- centage of clean water is poured ; the material on the outer edge is turned into the center by the aid of a trowel. As soon as the water has been absorbed, which should not require more than i minute, the operation is completed by vigorously kneading with the hands for i minute.
