'Cbe Conservative. deep enough under water to strike below the armored bolt. In the pointed nose of the 'weapon is a plunger which is driven home upon contact , igniting the priming , which in turn ignites and ex plodes the 150 pounds of wet gun cotton. The torpedo is prevented from diving or rising to the surface during its run by the action of a horizontal rudder which is controlled by the pressure of the column of water above it. If the tor pedo attempts to leave the depth to which it is adjusted , this horizontal rud der is acted upon by the varying pressure and the torpedo is brought back to its proper depth. The cost of a Whitehead torpedo is about $3,000. THE LORDS AND When Mr. Rich- THK MOON. ard Harding Davis is in London , and can spare the time , he visits the terraces of the Houses of Par liament , where he drinks tea with lords , who stop legislating for that purpose. It was while thus engaged that he observed the moon rising behind St. Pnxil's , as is recorded in the book which he afterward wrote upon the subject. Now St. Paul's lies northeast from the terraces of the Houses of Parliament. OLD POST ROADS. Major Lewis Downing has recently had pleasant cor respondence with Mr. George F. Ives , of Danbury , Conn. , a well-known col lector of Americana. Mr. Ives is just at present particularly interested in all that relates to the old days of stage coaching in New England , and it is with regard to the history of the Concord coaches that he has been communicat ing with Major Downing , who , as head of the Abbot-Downing Company , prob ably knows more about those vehicles than any one else alive. Major Downing sent Mr. Ives some photographs of old coaches , and in re turn received a photograph which is such a curiosity as to bo well worth extended description. The original of this photograph was an old handkerchief , printed in 1815 by R. Gillespio , at "An- derston Printfield , near Glasgow. " Around the edge is a very neat and pretty floral border , with the arms of the United States , the front and reverse of the dollar of 1815 , a quartette of ships of war , and portraits of Washington , Adams , Jefferson , and "Maddisoii" intertwined. Its title is "A Geographical View of All the Post Towns in the United States of America and Their Distance from Each Other According to the Establish ment of the Postmaster General in. the Year 1815. " By an ingenious arrange ment of the towns on the main coast line and those on the cross post roads , the distance from one of these posts to any other could easily bo ascertained. The "main line of post towns" extended "from Passamaquoddy in the District of Maine 'to Sunbury in the State of Georgia. " Portsmouth was thoonly New Hampshire town on this main line , having York , Wells , Biddoford , and Portland on iho one side and "Nowbury Port , " Ipswich , Salem , and Boston on the other. The first of the cross post roads given on the map led from Portsmouth to Exeter , 15 miles , to Concord , 40 miles more , to Hanover , GO miles more , mak ing a total of 115 miles from Portsmouth to Hanover. Other New England cross roads were from Salem to Gloucester , Boston to Nantucket , Boston to Barii- stable , Boston to Newport , Newport to "Newhavon , " Boston to Providence , SpringfiOld to Hanover , Boston to Haii- over , Boston to Albany , Boston to Que bec , and Northampton to Williamstown. Springfield to Hanover was by way of Northampton , Deerfield , Greenfield , " " Westminster Charles- "Brattleburgh , , - town , Windsor , and Hanover. The Boston post for Hanover went by way of Concord , Mass. , Groton , Ashburn- ham , Newmarlboro , Walpole , Charles- town , Cornish , and Lebanon. The dis tance from Springfield to Hanover was 126 miles and from Boston to Hanover 147 miles. The object in publishing such a table as this was to make it possible for the people to compute easily and with a handy helper what the cost of postage on any letters they might chance to write would be. Nowadays we stick a two-cent stamp in the corner of an en velope , and post the letter without fur ther thought if it is going anywhere in this broad laud , to Tacoma , to El Paso , or any other distance , however much greater than the extreme limit of 1815 , Passamaquoddy to Sunbury. But in that year , 82 years ago , the postoffice department was run on other lines. The following "rates of postage" are given on the old handkerchief : "Single Letter conveyed by laud for any distance not exceeding 10 Miles , 6 cents. Over 10. not exceedincr GO miles , 8 cents. " GO " t" 100 " 10 " " 100 " " 150 " 12 " " 150 " " 200 " 15 " 200 " " 250 " 17 " 11 250 " " 850 " 20 " " 050 " " 450 " 22 " For 450 25 " Double letters are charged double and triple letters , triple of these rates.

Its owner has had but two photographs finished from the plate , with the intention of keeping the repro ductions raro. Major Downing is cer tainly fortunate in having received one of them as a present. Concord , N. H. , Monitor. A GLORIFICATION 111 first pUlCO , OI'STAGK-DRIVKKS. there is magic ill the calling of a stage-driver. Every body knows and aspires to know the stage-driver ; everybody is Iniowii by , and is proud to be known by the stage- driver. The little boys remember it a mouth , if the stage-driver speaks to them. There is a particular satisfaction to bo able to distinguish among drivers and say it was Winkle , or it was Hiiies , or it was Mitchell. Of all the people on the earth , he is the one who rolls by in a gilded coach ; he is the ouo who sweeps it high and dry over the world ; he is the one who rides through his immense estate with the most lordly and consequential quential air , and all the rest of us seem to bo but poor tenants and gaping boors. It is sometliing to speak to a stage- driver ; it is a great thing to bo able to joke with him. It is a sign of a great man to be recog- uizecl by the stage-driver. To be , per chance , laiown by one who knows nobody is nothing ; to bo known , to be pointed out , to have your name whis pered in a by-staudcr's ear by one who laiows everybody , affects you as if Omniscience were speaking about you. The stage-driver differs from the steam boat captain in that the latter is not seen to bo so immediately connected with his craft as the former. Wo meet the cap tain at the breakfast table ; he is nobody ; ho is no more than wo ; we can eat as well as ho can. But who dare touch the stage-driver ? Who dare swing his whip ? How rapidly and securely he drives down one hill and up the next and that with fifteen passengers and a half ton of baggage ! Then how majestically ho rounds to at the door of the tavern ! What delicate pomp in the movement of the four handsome horses ! In what style the cloud of dust , that has served as an outrider all the way , passes off when the coach stops ? How the villa- gerstho blacksmith , the shoemaker , the thoughtful politician , and the boozy loafers that fill the stoop grin and stare and make their criticisms ! How ho flings the reins and the tired horses to the stable-boy , who presently returns with a splendid relay ! How ho accepts these from the boy , with that sort of air with which a long might bo
