the report made in 1874 to the special Works Com-
mittee of Southampton, by Mr. James Lemon, C.E.,
Borough Surveyor. He says:—
“ The principle adopted by the Improved Wood
“ Pavement Company, namely, two thicknesses of
“ boarding bedded on sand, at first sight has very
“ much to recommend it. It enables the engineer to
“ obtain ready access to gas and water pipes. It
“ distributes the weight of heavy loads over a large
“ surface, and what is perhaps more important in
“ London, the pavement can be laid and. repaired
u with great rapidity without much hindrance to
“ traffic. But it has in my mind many glaring de-
u fects; viz. its liability to rapid decay; its want of
“ solidity, and the encouragement it gives to a damp
“ subsoil. It must be evident that a wood pavement
“ which is not water-tight or kept dry underneath,
“ must contain all the elements of decay, more espe-
“ cially when the substratum is sand, and the water
“ and urine which finds its way through the joints
“ can pass freely under the boarding, rendering it
“ wet and damp. It is true the Company caulk the
“ joints with pitch and tar, but the end joints are
“ open and the water can pass freely through them.”
“ The want of solidity in the pavement is apparent
“ if it is continually watched under heavy loads, the
“ two thin boards on a soft bed must necessarily
“ yield under great pressure, and in places a per-
“ manent set or depression must be the result.”
