The greater part of the streets are what may be termed pebble-roads, a name which describes exactly what they are. At this moment, in the whole city, there are upwards of seven hundred and seventy-two thousand square sagenes[2] of these roads, while of stone pavement there are only nine thousand four hundred and fifty, and of wood six thousand four hundred. [Footnote 2: A sagene is seven feet.] The wooden pavement, I believe, is peculiar to St. Petersburg, and merits a description. It consists of small hexagons sawed from a piece of resinous wood, and laid into a bed formed of crushed stones and sand. These are fastened laterally into each other with wooden pegs, and when the whole forms a plain surface, the interstices are filled with fine sand, and then boiling pitch is poured over all. This pitch from the porous nature of the wood is speedily absorbed, and on a quantity of sand being strewed above it, the operation is complete, and a pavement constructed which is found to be extremely durable, and which seems to me to suffer much less injury from the frost than the stone causeway. The honor of the invention is due to M. Gourief; and I have no doubt he will ultimately see it adopted in most of the great towns towards the north. {517} SUPPLEMENT. In compliance with the suggestion of many of our friends, and at the request of a majority of our contributors, we again publish a supplement consisting of _Notices of the_ “_Messenger_.” We have duly weighed the propriety and impropriety of this course, and have concluded that when we choose to adopt it, there can be no good reason why we should not. Heretofore we have made selections from the notices received—only taking care to publish what we conceived to be a fair specimen of the general character of all—and, with those who know us, no suspicion of unfairness in this selection would be entertained. Lest, however, among those who do _not_ know us, any such suspicion should arise, we now publish _every_ late criticism received. This supplement is, of course, not considered as a portion of the Messenger itself, being an extra expense to the publisher. We commence with the _Newbern (North Carolina) Spectator_—a general dissenter from all favorable opinions of our Magazine.
