While for many reasons the cobble-stone is an excellent pavement for thespace between the rails, yet, as ordinarilylaid, the best laid of that ordiuaiy cobblefoot-way soon looks like a relief map of themoon. The stones being of unequal size, thesmall ones sink deeper into the bed than thelarge ones; hence, those which offer mostresistance to foothold and traction and givethe roughest riding to ordinary vehicles. It is necessary to bed the largest stonesnext the stringers to give the stringer andrail lateral stiffness; but the rest of thecobbles are generally put in higgledy-pig-gledy, without reference to their size andshape. If, now, the cobbles were sorted more,laying the very largest in a row next thethe stringers, and the next largest in alengthwise row next. that, and so on, withthe smallest in the center, the road being-made with e
