might indicate either a too early opening of the steam valve, thereby admitting steam in the cylinder before the piston had completed the stroke; or a too early closing of the exhaust at that end of the cylinder, thus causing excessive compression; either of which would also cause a loss of efficiency and power.

Most types of indicators after their being in use for a length of time, are liable to certain defects, or disarrangement more or less in their pencil movement; (and these defects sometimes appears in new instruments) and which prevents the initial pressure or vertical line as traced upon the paper, from being at a right angle or perpendicular to the atmospheric line; and in such case the instrument is usually designated as out of square.

As a consequence, the admission line at either end of the diagram, will be inclined to the perpendicular, as appears by
