These wines of the Moselle are, to be sure, secondary to those of the vineyards of the Rhine and the Main, but the varieties are very numerous.

A Dutch burgomaster once bought of the Abbey of Maximinus—a famous wine-growing establishment as well as a religious community—a variety known as Gruenhaüser, in 1793, for eleven hundred and forty-four florins a vat of something less than three hundred gallons. It was known as the nectar of Moselle, and "made men cheerful, and did good the next day, leaving the bosom and head without disorder." Such was the old-time monkish estimate and endorsement of its virtues.

BONN

Bonn in the popular mind is noteworthy chiefly for its famous university, and for being the birthplace of Beethoven.

The city was one of the fifty fortresses built by Drusus on the Rhine, and the only Rhenish city, with the exception of Cologne, which has kept its Roman appellation. It is mentioned by Tacitus both as Bonna and Bonensia castra.

The cathedral is as famous as the university. It was funded by the mother of Constantine the Great, who, according to tradition, consecrated the primitive church here in 319.

Really, it is not a very stupendous pile, the present cathedral, but it looks far more imposing than it really is by reason of its massive central tower and steeple.
