IMPROVEMENT IN PRINTING MACHINERY.

This is the design of Alfred Godfrey, of Clapton. According to this

improvement, as represented at Figs. 1 and 2, a rack, A, is employed

vibrating on the pivot a, and a pinion, a1, so arranged that instead of

the pinion moving on a universal joint, or the rack moving in a parallel

line from side to side of the pinion at the time the motion of the table

is reversed, there is employed, for example, the radial arm, a2, mounted

on the shaft, a3, supporting the driving wheel, a4. The opposite or

vibrating end of the radial arm, a2, supports in suitable bearings the

pinion, a1, and wheel, a5, driving the rack through the medium of the

driving wheel, a4, the effect of which is that through the mechanical

action of the vibrating arm, a2, and pinion, a1 in conjunction with the

vibrating movement of the rack, A, an easy, uniform, and silent motion

is transmitted to the rack and table.

A CHARACTERISTIC MINING "RUSH."--THE PROSPECTIVE MINING CENTER OF

SOUTHERN NEW MEXICO.

A correspondent of the _Tribune_ describes at length the mining camps

about Lake Valley, New Mexico, hitherto thought likely to be the central

camp of that region, and then graphically tells the story of the recent

"rush" to the Perche district. Within a month of the first strike of

silver ore the country was swarming with prospectors, and a thousand or

more prospects had been located.

The Perche district is on the eastern flanks of the Mimbres Mountains,

a range which is a part of the Rocky Mountain range, and runs north and

south generally parallel with the Rio Grande, from which it lies about

forty miles to the westward. The northern half of these mountains is

known as the Black Range, and was the center of considerable mining

excitement a year and a half ago. It is there that the Ivanhoe is

located, of which Colonel Gillette was manager, and in which Robert

Ingersoll and Senator Plumb, of Kansas, were interested, much to the

disadvantage of the former. A new company has been organized, however,

with Colonel Ingersoll as president, and the reopening of work on the

Ivanhoe will probably prove a stimulus to the whole Black Range. From

this region the Perche district is from forty to sixty miles south. It

is about twenty-five miles northwest of Lake Valley, and ten miles west

of Hillsboro, a promising little mining town, with some mills and about

300 people. The Perche River has three forks coming down from the

mountains and uniting at Hillsboro, and it is in the region between

these forks that the recent strikes have been made.

On August 15 "Jack" Shedd, the original discoverer of the Robinson mine

in Colorado, was prospecting on the south branch of the north fork of

the Perche River, when he made the first great strike in the district.

On the summit of a heavily timbered ridge he found some small pieces of

native silver, and then a lump of ore containing very pure silver in the

form of sulphides, weighing 150 pounds, and afterward proved to be worth

on the average $11 a pound. All this was mere float, simply lying on the

surface of the ground. Afterward another block was found, weighing 87

pounds, of horn silver, with specimens nearly 75 per cent. silver. The

strike was kept a secret for a few days. Said a mining man: "I went up

to help bring the big lump down. We took it by a camp of prospectors who

were lying about entirely ignorant of any find. When they saw it they

instantly saddled their horses, galloped off, and I believe they

prospected all night." A like excitement was created when the news of

this and one or two similar finds reached Lake Valley. Next morning

every waiter was gone from the little hotel, and a dozen men had left

the Sierra mines, to try their fortunes at prospecting.

As the news spread men poured into the Perche district from no one knows

where, some armed with only a piece of salt pork, a little meal, and a

prospecting pick; some mounted on mules, others on foot; old men and men

half-crippled were among the number, but all bitten by the monomania

which possesses every prospector. Now there are probably 2,000 men in

the Perche district, and the number of prospects located must far exceed

1,000. Three miners from there with whom I was talking recently owned

forty-seven mines among them, and while one acknowledged that hardly one

prospect in a hundred turns out a prize, the other millionaire in embryo

remarked that he wouldn't take $50,000 for one of his mines. So it goes,

and the victims of the mining fever here seem as deaf to reason as the

buyers of mining stock in New York. Fuel was added to the flame by

the report that Shedd had sold his location, named the Solitaire, to

ex-Governor Tabor and Mr. Wurtzbach on August 25 for $100,000. This was

not true. I met Governor Tabor's representative, who came down recently

to examine the properties, and learned that the Governor had not up to

that date bought the mine. He undoubtedly bonded it, however, and his

representative's opinion of the properties seemed highly favorable.

The Solitaire showed what appeared to be a contact vein, with walls of

porphyry and limestone in a ledge thirty feet wide in places, containing

a high assay of horned silver. The vein was composed of quartz, bearing

sulphides, with horn silver plainly visible, giving an average assay of

from $350 to $500. This was free milling. These were the results shown

simply by surface explorations, which were certainly exceedingly

promising. Recently it has been stated that a little development shows

the vein to be only a blind lead, but the statement lacks confirmation.

In any case the effect of so sensational a discovery is the same in

creating an intense excitement and attracting swarms of prospectors.

But the Perche district does not rest on the Solitaire, for there has

been abundance of mineral wealth discovered throughout its extent. Four

miles south of this prospect, on the middle fork of the Perche, is an

actual mine--the Bullion--which was purchased by four or five Western

mining men for $10,000, and yielded $11,000 in twenty days. The ore

contains horn and native silver. On the same fork are the Iron King and

Andy Johnson, both recently discovered and promising properties, and

there is a valuable mine now in litigation on the south fork of the

Perche, with scores of prospects over the entire district. Now that one

or two sensational strikes have attracted attention, and capital is

developing paying mines, the future of the Perche District seems

assured.
