“For a Method of Securing Ranges of Short Plank in Pavements, – Joseph E. Ware, St. Louis, Missouri, February 11.
The nature of this invention and improvement consists in method of securing certain parts of planking on streets in such a manner as to permit their removal, so as to reach pipes or sewers underneath; the planks being cut in short pieces for such ranges, and with such bevels or overlaps as to cause one piece to aide in holding down the other.
Claim.— What I claim as my invention, is the method above described as securing ranges of short pieces of planking of a street or road in longitudinal lines over water or gas pipes, by means of screws or keys with staples, aided by the double bevel of the short planks, and the ends of the permanent interval planks holding and permitting of the easy removal of such a short piece.”

A development that should have been improved upon and carried on today. We hear on the news media several times a year that a contractor hits a gas line with a digger and blows up half the city.
