oew and profitable Experiments as come to your 
knowlcdgej take the liberty to inform you of a New Invcns

and advantage to the public: But the waiting for a full trial 
of thofe Experiments offered at for the worlds fatisfaftion, 
and the continuance of the late War (which is a very bad 
Nurfeto Trade or Projefts ) has been the reafon the Work 
has yet advanced no farther. Some few years fince,Sr* Phik

and durable then the way of Boards^Pitch^TarjRoziOj 8rim-
