Dr. Sarrajin fays, that he was never able to dif-

by thrufting down Stakes of five or fix Feet long, 
and as thick as one's Arm, pretty deep into the 
Ground j thefe they will wattle a-crofs with tender 
pliable Boughs, and fill up the Spaces with Clay, 
making a Slope on the Side againft which the Water 
preffes, but leaving the other perpendicular. They 
make their Houfes after the fame manner j the Walls 
are upright, two Foot thick, and at Top in Form of 
a Dome j they are^ ufually oval, five or fix Feet
