Meantime, watch for a sign from me. Eight days from now, we shall be
wide asunder; for I shall be on the border of the Pacific, and you far
out on the Atlantic, approaching England. That day, if I am alive and my
sublime discovery is proved and established, I will send you greeting,
and my messenger shall deliver it where you are, in the solitudes of the
sea; for I will waft a vast sun-spot across the disk like drifting smoke,
and you will know it for my love-sign, and will say "Mulberry Sellers
throws us a kiss across the universe."

WEATHER FOR USE IN THIS BOOK.

Selected from the Best Authorities.

A brief though violent thunderstorm which had raged over the city was
passing away; but still, though the rain had ceased more than an hour
before, wild piles of dark and coppery clouds, in which a fierce and
rayless glow was laboring, gigantically overhung the grotesque and
huddled vista of dwarf houses, while in the distance, sheeting high over
the low, misty confusion of gables and chimneys, spread a pall of dead,
leprous blue, suffused with blotches of dull, glistening yellow, and with
black plague-spots of vapor floating and faint lightnings crinkling on
its surface. Thunder, still muttering in the close and sultry air, kept
the scared dwellers in the street within, behind their closed shutters;
and all deserted, cowed, dejected, squalid, like poor, stupid, top-heavy
things that had felt the wrath of the summer tempest, stood the drenched
structures on either side of the narrow and crooked way, ghastly and
picturesque, under the giant canopy. Rain dripped wretchedly in slow
drops of melancholy sound from their projecting eaves upon the broken
flagging, lay there in pools or trickled into the swollen drains, where
the fallen torrent sullenly gurgled on its way to the river.

The fiery mid-March sun a moment hung
Above the bleak Judean wilderness;
Then darkness swept upon us, and 't was night.

The quick-coming winter twilight was already at hand. Snow was again
falling, sifting delicately down, incidentally as it were.

Merciful heavens! The whole west, from right to left, blazes up with a
fierce light, and next instant the earth reels and quivers with the awfu
