| || The Contractor in excavating the cuttings and forming the embankments shall carry out the same in accordance with the longitudinal and cross sections and strictly adhere to the depths and heights figured thereon. The slopes shall be formed to an inclination of 1½ feet horizontal to 1 foot perpendicular for cuttings (except where otherwise shewn on the scross cross sections) and also for embankments, but should the engineer be of opinion that an increased or flatter slope than that shewn on the cross sections in any of the cuttings or embankments is desirable no extra price per yard will be paid to the Contractor for any increase in the excavations or alterations of embankments.The plan shows the direction of the railway and the area of land that will be purchased by the Companyand upon portions of which the Contractor will with the consent of the Engineer in writing be allowed to erect all necessary machinery temporary houses offices &c for the execution of the works.The red line on the longitudinal section shews the formation lines for the bottoms of the excavations and the level for the top of the embankments & bridges previous to the laying on of the ballast in preparation for the permanent way.The widths of the embankments and cuttings when soiled at the level of formation are severally marked upon the enlarged cross section (drawing no 4) and the dimensions so specified shall in no case be deviated from without the approval of the Engineer in writing.Each embankment shall be carried forward uniformly and be of the dimensions shown on the sections, or such altered inclination of the slopes as the Engineer may consider necessary due allowance being made in the height of the embankment for shrinkage.The side tips shall be kept well in advance of the centre tip.The Contractor shall during his contract remedy any slips and remove any weak or soft spongy parts from the site of the embankments. After the embankments have consolidated the slopes of same and of cuttings shall be neatly trimmed to the proper line before being soiled. In carrying the embankment up to or over bridge or culvert great care shall be used by staging backing and punning so as to cause no unequal pressure or damage to the work. No mud slurry or soft material shall be put into the embankment. The slopes of all embankments and cuttings where ordered shall be sown with grass seed 3½ bushels per acre.Should any spongy or unsound material appear in the cuttings the same shall be removed and if any water springs or leakage appear they shall be carried off as directed by the Engineer.
