It extended from the rear of the premises to the sewer, a distance of 75 feet, and was at the bottom of a very narrow cutting, as m the figure It was a 6m. earthenware pipe drain; and considermg the width of the cutting 1 Fig. 87. in which it was laid it was not surprising to find all the joints imperfect.
