ch has been adopted by
Campbell, not Mrs. Hemans, and charmingly set to music by Mrs. Arkwright,
is well known on the Rhine. There are two poems on the legend in Simrock's
_Rheinsagen_ (12mo., Bonn, 1841), one by the editor, and another by August
Kopisch. They exactly accord with Campbell's poem.

The legend of Ritter Toggenburg resembles that of Roland in many
particulars, but it is not the same, and it belongs to another locality, to
Kloster Fischingen, and not to Nonnenwerth. "Roland the Brave" appears in
all the later editions of Campbell's _Poems_. Simrock's _Rheinsagen_ is one
of the most delightful handbooks that any one can take through the romantic
region which the poems (partly well selected by the editor, and partly as
well written by himself) describe.

The author of the beautiful lines which are quoted by your correspondent
X. Y. Z., is Campbell, not Mrs. Hemans. The poet, in the fifth stanza of
his ballad, tells how the unfortunate Roland, on finding that Hildegund had
taken the veil, was accustomed to sit at his window, and "sad and oft" to
look "on the mansion of his love below."

"There's yet one window of that pile,
Which he built above the nun's green isle;
Thence sad and oft look'd he
(When the chant and organ sounded slow)
On the mansion of his love below,
For herself he might not see.

"She died! He sought the battle plain,
Her image fill'd his dying brain,
When he fell and wish'd to fall;
And her name was in his latest sigh,
When Roland, the flower of chivalry,
Expired at Roncevall."

F. M. MIDDLETON.

Scott has, in _Marmion_,--

"When Roland brave, and Olivier,
And every paladin and peer,
At Roncesvalles died!"

I quote from memory, and have not the poem.

_Recovery of Silver._--As many correspondents of "N. & Q." have asked how
to recover the silver from their nitrate baths when deteriorated or
spoiled, perhaps the following hints may be acceptable to them. Let them
first precipitate the silver in the form of a chloride by adding common
salt to the nitrate solution. Let them then filter it, and it may be
reduced to its metallic state by either of the three following methods.

1. By adding to the wet chloride at least double its volume of water,
containing one-tenth part of sulphuric acid; plunge into this a thick piece
of zinc, and leave it here
