At the priory, there is a powerful steam engine, belonging to Mr. Benson; and on the road to Birmingham is a brewery, belonging to a public company.  In the environs are numerous mines of coal, ironstone, and lime; which land, where the mines have not been worked, sells in general for about one thousand pounds per acre.—­Nails and heavy iron-work employ a great part of the population.

The ancient castle, of which there still remains the keep and the gateway, is said to have been erected about the year 700, by a person named Dodo, from whom the name of the town is derived.  Underneath the hill, whereon the castle was situated, there are stupendous caverns, from whence the lime stone has been conveyed away, which are truly august, being of considerable extent, and proportionably high; the roof being supported by rude pillars of vast dimensions, which have been left by the miners for that purpose.  There is one tunnel that perforates the hill entirely, being in length near two miles:  it is in height thirteen feet, in width nine feet, and in one part sixty-four feet below the surface.

These enormous subterranean works, with the method of procuring the stone, are highly deserving the attention of strangers, who have there an opportunity of seeing this useful article forced from its natural situation by means of gunpowder; raised from the bowels of the earth, and conveyed through the country by means of inland navigation, to serve the purpose of the agriculturist, and also the architect.  In these rocks there are numerous marine productions, and among others, one which the miners denominate a locust, for which they have been known to refuse its weight in gold; it being understood that there is only one other place in the kingdom where they are to be found.  The mines of coal in this vicinity are from ten to twelve yards in thickness, which circumstance it is said does not take place in any other part of the kingdom.  A stranger approaching Dudley after it is dark, will be astonished to see the numerous fires in different directions, which proceed from the furnaces, forges, and collieries; the latter converting their small coal into coke.

The noble proprietor of these extensive mines and the ruins above them has for several successive years planted innumerable trees of different kinds around the castle hill, and during last summer (1818) he caused avenues to be cut through them, which form the most romantic, picturesque, and diversified shady walks, extending over numerous hills and dales, that can be imagined; the views that occasionally present themselves when least expected, are enchanting, and when you arrive at the summit, there is a most extensive prospect over the counties of Worcester, Stafford, Derby, Leicester, Warwick, Salop, Hereford, and part
