What angler has not been, if he be not still, a reader of Izaak Walton? And what reader of Izaak Walton has not observed his frequent quotations from Dubravius, and been amused by that wonderful account of the victory of a frog over a pike, of which Dubravius declares he was himself an eye-witness, but which reads far more like a dream than a reality? And the name of this same Dubravius has lately been brought before the public by Mr. Frank Buckland, as that of the author of an excellent recommendation in the management of fish-ponds, a means of producing food so sadly neglected in this country, viz.: to draw off the water every third or fourth year and sow a crop of oats on the rich mud collected at the bottom. It may not therefore be uninteresting, if I give a brief account of the life and writings of Dubravius, who was a man of considerable mark in his day in the political and ecclesiastical, as well as in the pisci-cultural world.
