In the time of Edward III. this "Castle of the Peak" reverted to the Crown, but now it is held by the Duke of Devonshire. Under the hill on which the ruins stand is the "Cavern of the Peak," with a fine entrance in a gloomy recess formed by a chasm in the rocks. This entrance makes a Gothic arch over one thousand feet wide, above which the rock towers nearly three hundred feet, and it is chequered with colored stones. Within is a vast flat-roofed cavern, at the farther side being a lake over which the visitors are ferried in a boat. Other caverns are within, the entire cave extending nearly a half mile, a little river traversing its full length. There are more and similar caverns in the neighborhood.

[Illustration: HARDWICKE HALL.] One of the great characters of the sixteenth century was Elizabeth, Countess of Shrewsbury, familiarly known as "Bess of Hardwicke," where she was born, and who managed to outlive four husbands, thus showing what success is in store for a woman of tact and business talent. She was a penniless bride at fourteen, when she married an opulent gentleman of Derbyshire named Barley, who left her at fifteen a wealthy widow. At the age of thirty she married another rich husband, Sir William Cavendish, the ancestor of the Dukes of Devonshire, who died in 1557, leaving her again a widow, but with large estates, for she had taken good care to look after the proper marriage settlements; and in fact, even in those early days, a pretty good fortune was necessary to provide for the family of eight children Sir William left her. She next married Sir William Loe, who also had large estates and was the captain of the king's guard, the lady's business tact procuring in advance of the wedding the settlement of these estates upon herself and her children--a hard condition, with which, the historian tells us, "the gallant captain, who had a family by a former marriage, felt himself constrained to comply or forego his bride." But in time the captain died, and his estates all went to the thrifty lady, to the exclusion of his own family; and to the blooming widow, thus made for the third time, there came a-courting the Earl of Shrewsbury; the earl had numerous offspring, and therefore could hardly give Bess all his possessions, like her other husbands, but she was clever enough to obtain her object in another way. As a condition precedent to accepting the earl, she made him marry two of his children to two of hers, and after seeing these two weddings solemnized, the earl led her to the altar for the fourth time at the age of fifty; and we are told that all four of these weddings were actual "love-matches." But she did not get on well with the earl, whose correspondence shows she was a little shrewish, though in most quarrels she managed to come off ahead, having by that time acquired experience. When the earl died in 1590, and Bess concluded not again to attempt
