An important matter to be ascertained in reference to allindicators; is, whether the vertical or admission line on thediagram, made by the pencil (when in contact with the paperon the drum) is exactly perpendicular to the atmospheric, orhorizontal line, that is made by the pencil, when in contactwith the drum while rotating. A leaning of the admission line either forward or back,thereby causing it to be out of square with horizontal line,tends to be misleading in reference to the proper adjustmentof the valves, especially if a fault of this kind exists in the And Its Appliances. 149 instrument, and not previously known. This fact may easily bedetermined at any time before placing the spring in the instru-ment, by simply placing the paper upon the drum the same as. for taking diagrams, and bring the pencil in contact with it;then cause the drum to rotate once back and forth by meansof the cord attached to the indicator, thereby making a hori-
