mense reservoirs which contained the combustible liquid. It was only necessary to demolish a piece of wall in order to allow it to flow out in a vast stream.
This had been done that night, a few hours previously, and this was the reason that the raft which carried the true Courier of the Czar, Nadia, and the fugitives, floated on a current of mineral oil. Through the breaches in these reservoirs of enormous dimensions rushed the naphtha in torrents, and, following the inclination of the ground, it spread over the surface of the river, where its density allowed it to float.
