Railway building was begun in the state in 1836 with the Raleigh & Gaston line, opened from Raleigh to Gaston in 1844 and extended to Weldon in 1852.
A longer line, that from Wilmington to Weldon, was completed in 1840.
The Roanoke river is navigable to Weldon and the Cape Fear river to Fayetteville; the Neuse is navigable for small vessels only to Newbern.
On the decisive theatre the Federals made their way, little by little and at a heavy cost, to the Weldon railway, and beyond it to the westward.
One more attempt to outflank Lee to the westward was made by Grant without success, before winter came on, and the campaign closed with an expedition, under the direction of General Warren, which destroyed the Weldon line.
Magnesium oxychloride when heated to redness in a current of air evolves a mixture of hydrochloric acid and chlorine and leaves a residue of magnesia, a reaction which is employed in the Weldon-Pechiney and Mond processes for the manufacture of chlorine.

We quote from the article "Variation and Selection," in the tenth edition of this Encyclopaedia, an exposition of the biometric method by Weldon: The characters of individual animals or plants depend upon so many complex conditions, most of which are generally unknown to us, that the statements we can make concerning them are of a peculiar kind.

The difficulty was only overcome by the Weldon process, being the inventions of Walter Weldon from 1866 onwards, and his process up to this day furnishes the greater proportion of chlorine manufactured in the world.
The Deacon process, like the Weldon process, effects its object by the oxidizing action of atmospheric air, but in a very different manner.
Weldon retained the principle of the Scheele FIG.
Weldon Chlorine Still.
The Deacon process makes cheaper chlorine than the Weldon process, but the plant is complicated and costly and the working requires a great deal of attention.
Owing to the reduction in the supply of available hydrochloric acid (on account of the increasing use of the "ammonia-soda" process in place of the "Leblanc" process for the manufacture of soda) Weldon tried to adapt the former to the production of chlorine or hydrochloric acid.
However, in conjunction with Pechiney, of Salindres (near Alais, France), the Weldon-Pechiney process was worked out.
This acid must, therefore, be condensed in the ordinary way into liquid hydrochloric acid and formerly could be worked up only by the Weldon process.
Chlorine, generated in an ordinary or a Weldon still, is passed in and is rapidly absorbed.
