Page 419 - ... long. The fascines are laid in alternate layers crosswise and lengthwise, and the layers are either connected by pickets, or else the withes, with which the fascines are bound, are cut to allow the brushwood to form a uniform and compact bed. This method of securing a good bed for structures on a weak wet soil has been long practised in Holland, and experience has fully tested its excellence.
