In working pol-ishing machines thechief points to beobserved are to usesoft and flexiblebelts, that will hug the small pulleys closely and notjump and jerk when any heavy strain comes upon themsuddenly and to keep the bearings well babbitted and.

Bearings not provided with closed oil cups shouldhave covers of tin or brass over the oil holes andthe foreman should see that the covers are kept inplace. If there is room for it in the cups, a littlecotton waste laid in them and changed as fast as itgets dirty will do a good deal towards keepingemery out of the bearings of all machinery in thepolishing room. Where possible the machines should be arranged sothat the workmen stand facing the light, as this permitsthem to see what they are doing without stopping andturning their work about, thus enabling them to do morework in a given time than they could if the light camefrom another direction. This may seem a trivial matter,but any polisher will assure you that it is not, and in abusiness where the chief expenditure is for labor, everysaving of time is
