not possible cotton may be stowed in the same hold with these substances provided the substances and the cotton are separated by clean dunnage or other cargo of a non-combustible nature. When stowage within the same hold involves considerable amounts of these substances the rosin or pitch shall be floored off with at least two layers of one inch dunnaging and the cotton stowed above.
