The usual practice whenan order is given by a railroad company to furnish acertain tonnage of rail is to specify the length of railsdesired, 30 ft. or 33 ft. as the case may be, and toaccept up to ten per cent of the tonnage in short rails,down to 25 ft. lengths, diminishing by one foot succes-sively. Some of these short rails are used on the in-. American Loader side rail of curves in order to keep the joints brokenwith the other rails on the outside line. What extraones are not required for this work should be kept to-gether and used up on straight track, breaking jointsto the best advantage. When laid in a sag. When a piece of track is laidin a sag which it is intended soon to raise to grade,the rails should be laid with open joints and the OONSTRUCTION 13 splices loosely bolted, otherwise, when brought tograde the joints will become too tight, since a saggingtrack is longer than one which is laid accurately tograde. Change of line toward center of curve. In caseswhere the general change of line is made by moving acurved track inward several feet, dig out the materialwhich is used for filling between the ties for the fulldistance covered by the change in line, so that theties will not crowd against each other or injure thesurface by rising up. Before commencing to line,cut the track loose at the middle of the curve by re-mov
