2 William, who high upon the yard Rock'd with the billow to and fro, Soon as her well-known voice he heard, He sigh'd, and cast his eyes below; The cord slides swiftly through his glowing hands, And (quick as lightning) on the deck he stands.

First in its brazen cell reluctant roll'd Bends the dark spring in many a steely fold; 175 On spiral brass is stretch'd the wiry thong, Tooth urges tooth, and wheel drives wheel along; In diamond-eyes the polish'd axles flow, Smooth slides the hand, the ballance pants below.

The hills had been stripped of their trees, and their raw sides gored and perforated by great timber-slides and prospect holes.

Then, too, there is another matterthe big slides.

No one knows for a certainty, but a man who has lived in Panama almost since the French started the big ditch, claims to know a great deal about the slides and the causes of them.

He tells me that certain small slides, such as have been experienced, are followedalmost always after the same lapse of timeby a much larger one.

So if he wants us to go to Panama, and get views of the giant slides, volcanic eruptions, and so on, I, for one, think we ought to go.

Anyhow, the slides are always more or less likely to occur.

They practically put the French engineers, who started the Canal, out of the running, and even when the United States engineers started figuring they didn't allow enough leeway for the Culebra slides.

" "And yet slides occur even now," remarked Joe, dubiously.

" "And we're going to get one of those slides on our films?"

And waiting for one of those Culebra Cut slides is going to be like camping on the trail of a volcano, I think.

You're almost sure to be buried alive under one of the big Culebra slides, and we'll never see you again!" CHAPTER VIII OFF FOR PANAMA There was a moment of silence following Mr. Piper's gloomy prediction, and then Miss Shay, with a laugh, cried out: "Oh, what a shame!

"Andlookoutforthebig slides!" called Mr. Piper after them, as the steamer swung away from the pier.

"We'll have to leave it and take to the Canal or the jungle, to say nothing of standing up to our knees in dirt taking slides.

" "Do youerreally have to get very close to get pictures of the big slides?" asked Mr. Alcando, rather nervously, Blake thought.

"I said I was going to learn moving pictures and I amslides or no slides.

And it's here where those big slides have been?"

We want no more slides.

"I mean that more slides are likely to occur; are they not?" "Yes, worse luck!"

Indeed these bright pictures flashed on to the sheet as the visions of Nationalists are but the slides in a German magic-lantern, designed to keep Turkey amused, and it was with the same object that Ernst Marré, in his Die Türken und Wir nach dem Kriege, was bidden to make other pictures ready in case Turkey grew fractious or sleepy.

The spirit beats her mortal bars, As down dark tides, the glory slides, And star-like mingles with the stars.'

but it slides back.

In the case of large engines with valve casings suitable for long slides, an expansion joint in the valve casing should invariably be inserted, otherwise the steam, by gaining admission to the valve casing before it can enter the cylinder, expands the casing while the cylinder remains unaltered in its dimensions, and the joints are damaged, and in some cases the cylinder is cracked by the great strain thus introduced.

This end is attained by the use of ball and socket joints; and, to allow some end play, one piece of the pipe slides into the other like a telescope, and is kept tight by means of a stuffing box.
