The amplitude of vibration of the diaphragm of the telephone receiver in reproducing speech is about the one-twenty millionth of an inch. Holophane glass is a pressed glass resembling cut glass, having vertical prisms on the inside for diffusing the light and horizontal prisms on the outside for directing the light. Among the perils to which a sub v marine cable is subject are ocean cur " rents, which swirl against seabottom crags and the attacks of sea monsters, shurks, swordfish and the like. Among other improvements at the port of Boulogne, a French govern ment scheme provides for the con struction of an Atlantic steamer berth 920 feet long and 100 feet wide, with a water depth of 25 feet. The English cotton manufacturers, who have for so long a time depended on the United States for their raw ma terial, have raised a guarantee fund of $250,000 for the purpose of promot ing the cultivation of cotton within the British empire. The strait of Cansq, between. Cape Breton and the mainland of Nova Sco tia, is to be bridged. The task is an immense one, involving great engi neering difficulties, and the outlay of about $5,000,000. The bridge will be a cantilever, with a span of 1,800 feet, the longest in the world. A new process for the manufacture of artificial marble has been patented ■ in Berlin. Asbestos, dyeing materials, shellac and ashes are pounded into a stiff mass and then subjected to high pressure. The product is surprising ly firm and tough, not brittle, is very easily worked by means of tools, can be given a fine polish, and in appear ance cannot be distinguished from genuine marble. In the construction of a municipal electrical generating plant for the city of Geneva the engineers found them selves confronted with a great diffi culty in the constantly varying water level of the river Rhone. In order to overcome this inconstancy of the wa ter supply a two-storied station was constructed, with two turbines built above the other on the dynamo shaft. The plant comprises 18 sets of these turbines. The total capacity of the plant is 18,000 horsepower. GREAT NEWSPAPER ARMY. Immense Produc'tlveirn Shown by the Census Bureau on Printing und Publishing-, The census biflleiin on printing and publishing in the United States dur ing the year 1900 furnishes a good summary wherewith to judge the vast extent of Qie newspaper busi ness in this country. More thun a thousand million pounds of paper were Used to run off the various is sues, and a daily paper was supplied to each five inhabitants in the whole land, while a weekly or monthly reached each' two inhabitants, states the Baltimore News. A feature of the report is an ex tended account of the operations of the Associated Press, showing the great development of news-gutheriitg methods during the past two de cades. Almost the entire chapter on news-gathering organizations is de voted to a history and detailed de scription of the work of the Associat ed Press, which, the report says, was tlie leading organization in 18S0 and now "is far in the lead of the news gathering organizations of the United States." The report says that the Associat ed Press now has about 700 members, more than half of which are ufter noon dailies, and serves about 2,500 daily and weekly papers n addition. Most of the papers served are in the United States, but there are 50 or more in Canada, Mexico, Cuba and Porto Rico, in its regular news serv ice the Associated Press now uses 9,345 miles of leased wire by day and 20,467 miles by night. The annual revenues derived from assessments levied on the newspapers served ex ceed $1,950,000, and the number of words daily received and transmitted at each of the more important offices •er 50,000, or the equivalent is now of 35 columns of an average newspa per. For gathering foreign news tlie Associated Press lias contract rela tions with various foreign news agen cies, with which it exchanges news. Including other forms of publish 312 establishments. ing there were with a capital of $202,517,072 invested. This sum represents only the live capital utilized and the value of the land, buildings, tools, machinery aud Implements. The value of tlie prod ucts of the industry is returned at •t $347,055,050, to produce which in volved tin outlay of $36,090,719 for sal aries of officials, clerks, etc., $84,249, 889 for wages, $55,987,589 for miscel laneous expenses, including rent, taxes, etc., and $86,856,290 for mate rials used, mill supplies, freight and fuel. Of all newspaper and periodical es tablisnments, over 63 per cent, were owned by individuals, 20 per cent, in partnership, and only 17 per cent, by corporations.

San Franclioo Show, the LargMt Per* ceutaRe of Suiicides—(liieaito Hanks 111 I rd. I The number of people who voltuw tarily shuttled off this mortal coil in American and other cities during last year has been investigated by some driver in statistics and the following figures indicate the results: San Fran cisco leads with the largest ratio. 39.1 per 100,000 of population. Next comes another Pacific coast city. Los Angeles, with a ratio of 29.8. The reader has! naturally been looking for Chicago, and that cily does, in fact, come next with a ratio of 24.0, followed by the neighboring city of Milwaukee, whose ratio is 22.2. New Orleans was the scene of the self-destruction of 21.8 persons per 100,000 of population, and Cincinnati followed close with 21.2. New Haven is next with 20.9. and then comes the borough of Manhattan with 20.0, though greater New York as a whole is well down the list with a ratio of only 13 0. This îr less than Roches ter, Indianapolis, Philadelphia, Pitts burg. Baltimore, Boston. Detroit, Omaha and Louisville, besides all of those specifically enumerated above. As to the foreign cities. Paris leads the list with a ratio of 42, followed by Berlin 36, Vienna 28 and London 23. There were more suicides* in Saxony than in any other country. 31.1 per 100. 000. Tn Denmark the ratio was 25.8 in Austria 21.2. in France 15.7 in the Ger man emnire 14.3. and Sweden. Norway, Belgium. Great Britain. Italy, the United States and Spain followed in the order given. The table referring to American cities is somewhat difficult, to explain. Whv the city of the golden gate, and Cnlifnm'a. wi'h its glorious climate, its sunshine, its fruit and its flowers, should show tile greatfst number of suicides seems a mystery, unless the presence of a lnr<re Chinese nonulation explains it. The high suicide rate of Chionsro is. perhaps, accounted for bv the rush and struggle of that great city and the lar<re foreign element it contains—n foreign element, more over. which comes mainly from those countries where suicide is most fre nuent. The same is perhaps true of Milwaukee and of Cincinnati. The high rate at New Orleans may possibly be attributed to its relation to France and the ideas and traditions brought here from Paris, the suicide capital of the world. But New York city easts a cloud over some of these explana tions. Here are the large foreign pop ulations, the stress and strain of liv ing and working, the poverty, the ex citement. Yet Philadeluhia, the sleeping city of the humorous para graphes, has a higher ratio of sui cides than greater New York. And how is it to be exnlained that New Haven leads all the other New F n Ir land cities in the number of suicides? St. Paul and Minneapolis lie side by side, but in MinneanoTis the ratio is 11.4 and in St. Paul it is hut 6.5. It seems that the conclusion® must be that there is no method in suicide mad ness and that the effort to reduce it to rule is doomed to failure. n I Miners Exchange SALOON SB i] Choice Wines, Liquors and Cigars, etc. AN DR *3 W ERICKSON Proprietor.
