nt, double-fixed lights, and double-revolving white lights.
Colza oil is generally used, though the electric light, by its steady
brilliance, is likely to supersede all others, when very great
intensity is required.

Care has to be taken in the selection of the spot where the lighthouse
shall be built, for in some cases they are rendered useless by the
thick fogs that for the greater part of the year obscure their light.

Some mention may here be made of the most remarkable lighthouses on our
coast; and only to mention the words, is to suggest EDDYSTONE. No one
who has seen these dangerous rocks, could doubt that it is most
necessary to have a light fixed to them, for many a noble vessel has
been destroyed by running upon the perilous reef. No one, however, had
the courage or the enterprise to undertake the task, until an eccentric
gentleman of Littleberry, in Essex, generously came forward and offered
to do it. The work of Henry Winstanley, and his end, have been so
graphically and beautifully described by Jean Ingelow, that we take the
liberty to transcribe part of her poem. It tells first how the loss of
the "Snowdrop" troubled Winstanley:--

"'For cloth o' gold and comely frieze,'
Winstanley said, and sighed,
'For velvet coif or costly coat,
They fathoms deep may bide.

"'O thou brave skipper, blithe and kind,
O mariners bold and true;
Sorry of heart, right sorry am I;
A-thinking of yours and you.'"

The loss of the "Snowdrop" is followed by that of another ship, with
contents, and then--

"'I will take horse,' Winstanley said,
'And see this deadly rock,

"'For never again shall barque o' mine
Sail over the windy sea,
Unless, by the blessing of God, for this
Be found a remedy.'"

He went to the Mayor of Plymouth--

"'Lend me a lighter, good Master Mayor,
And a score of shipwrights free,
For I think to raise a lantern-tower
On this rock o' destiny.'"

"The old Mayor laughed, but sighed also,
'Ah, youth,' quoth he, 'is rash;
Sooner, young man, thou'lt root it out
From the sea that doth it lash.'"

Brave Winstanley however, was resolved to try, and after tedious
waiting, he commenced to work:--

"Then he and the sea began their strife,
And worked with power and might,
Whatever the men reared up by day,
The sea broke down by night.

"In fine weather, and foul weather,
The rock his arts did flout,
Th
