Function of the Tool Room.—In a broad sense it has beensaid that the prime function ofthe tool room is to act in thecapacity of an arsenal to pro-vide the management with thenecessary weapons to wage warupon excessive cost; the wordexcessive is here used to indi-cate any excess of cost beyondthat minimum at which it ispossible to produce the articleto be manufactured. Now andthen a master mechanic tells ushe has built and repaired en-gines without having any toolroom connected with the days gone by, successfulbattles were fought with clubs,bows and arrows; but whatchances would these same armiesstand with a modern armyequipped with modern weapons?An aim of every superintendentof motive power is to obtain themost extensive output possibleat the lowest cost, and the toolroom is perhaps the most impor-tant factor in bringing aboutsuch a result.—Mr. H.
