There was a great deal of enthusiasm among us about zinc, jack they call it down here, and the talk at first was all of the stupidity of Missourians in not getting at this part of their State, as well as the section about Joplin, in the search for ore.
If the tin is separated from an acid solution, the current must not be interrupted while the washing takes place, a precaution which it is not necessary to follow when the ammonium oxalate is used. When the tin is dissolved from the platinum dish, it acts like the zinc; that is to say, a black coating is left on the electrode.
I felt intensely happy. There lay the barge, the sun shining on the clean deck, and from the dewy edges of the old ropes, and from the barge-master's zinc basin and pail put out to sweeten in the air. "She won't leave us behind this time!" I cried, turning triumphantly to Fred. "Take care of the pie," said Fred.
But as the lightning is liable to melt the plate at the point where it enters, especially if the metal be tin or zinc, it is well to solder points at the angles. Some, "to make assurance doubly sure," carry the rods over the whole distance quite to the ground in addition. All authorities consider such a system as this to be as complete a defence against lightning as possible.
And here is an odd lane, and he looked at an alley which led down a sharp decline into a main street, where was to be seen the tricolor flag in zinc on a washhouse; he read the name: Rue de l'Ebre. He entered it, it was but a few yards long; the whole of one side was occupied by a wall, behind which were half seen some stunted buildings, surmounted by a bell.
Under this treatment the greater portion of the zinc that had been chemically dissolved by the potash is precipitated in the form of zinc hydrate, along with some carbonate. The liquid is now allowed to settle, and the clear supernatant solution is poured back again into the battery cells.
You can scrub it out with gasoline if it seems greasy, then with vinegar, if it is dark, then with metal polish, and so on; zinc tubs are really difficult to care for. A better way is to paint it all over with two coats of white paint and when it is dry enamel it. It costs only a dollar to do it, and it does save so much work; besides, a white tub always looks best of all.
I recall that Monsieur Ree-chard decreed a bain for B., which bain meant immersion in a large tin tub partially filled with not quite luke-warm water. I, on the contrary, obtained a speck of zinc ointment on a minute piece of cotton, and considered myself peculiarly fortunate.
"Now, according to what we set forth here," Steering tapped the paper, "the object and purpose of our corporation will be the mining of zinc and lead ore in the Canaan Tigmores. We are projecting upon the hypothesis that there is ore in the Tigmores, but we can't go too far upon hypothesis.
Take of gold, 4 parts; silver, 3 parts; copper 1 part; and zinc, 1 part. GOLD SOLDER No. 2 Take of gold, 3 parts; silver, 3 parts; copper, 1 part; zinc, 1/2 part. GOLD SOLDER No. 3 Take of gold, 2 parts; silver, 3 parts; copper, 1 part; and zinc 1/2 a part. The gold, silver, and copper must be fused in a crucible before the zinc is added, or else you cannot keep them in the vessel while heating.
