, and it was that of captivity, only to be ended by death.
She was immediately cut off from all communication with her subjects,
except such as it was deemed proper to allow; and was moved about from
place to place, the better to ensure her safety. The hapless victim
again and again implored Elizabeth to deal generously and justly with
her. "I came," said she, in one of her letters, "of mine own accord; let
me depart again with yours: and if God permit my cause to succeed, I
shall be bound to you for it." But her rival was unrelenting, and, in
fact, increased the rigours of her confinement. Whilst a prisoner at
Chatsworth, she had been permitted the indulgence of air and exercise;
and the bower of Queen Mary is still shown in the noble grounds of that
place, as a favourite resort of the unfortunate captive. But even this
absolutely necessary indulgence was afterwards denied; she was wholly
confined to the Castle of Fotheringay, and a standing order was issued
that "she should be shot if she attempted to escape, or if others
attempted to rescue her."

Burns, in his "Lament of Mary, Queen of Scots," touchingly expresses the
weary feelings that must have existed in the breast of the Royal
captive:--

"Oh, soon to me may summer suns

Nae mair to me the autumn winds
Wave o'er the yellow corn!
And in the narrow house of death,
Let winter round me rave;
And the next flowers that deck the spring,
Bloom on my peaceful grave."

TUBULAR RAILWAY BRIDGES.

In the year 1850, a vast line of railway was completed from Chester to
Holyhead, for the conveyance of the Royal mails, of goods and
passengers, and of her Majesty's troops and artillery, between London
and Dublin--Holyhead being the most desirable point at which to effect
this communication with Ireland. Upon this railway are two stupendous
bridges, which are the most perfect examples of engineering skill ever
executed in England, or in any other country.

The first of these bridges carries the railway across the river Conway,
close to the ancient castle built by Edward I. in order to bridle his
new subjects, the Welsh.

The Conway bridge consists of a tube, or long, huge chest, the ends of
which rest upon stone piers, built to correspond with the architecture
of the old castle. The tube is made of wr
