Ra mors concerning the Am) Arboi railroad are flying thick and fast. Last week it was to be cousolidated with the Ohio Centra). This week il is to become part of the P.ennsylavnia lines. Here is tuè latest f rom Detroit sources . No slight importaijce is attached by railroad meu to the trip tbrough this state last week of the officials of three Michigan lines Tbey went in a special train consisting of a Detroit, Grand Rapids & Western engine and private car and an Ann Arbor private car. The party consiste d of Charles M. Heald, president of the D. , G. R. & W. ; H. W. Ashley, general manager of the Anu Arbor, and S. T. Crap, general manager of the Flint & Pere Marquette. They vvere at Toledo, and on Friday went tbrongh Ann Arbor, northbonnd From a local railway official it is learned that their intention was to inspect every part of the three lines, and in Michigan Central circles it is said that there is a conibination on foot. These roads are the most important factor in reaching the northwest and the appcr part of the state, and it would ríe a powerfnl amalgamation. There is much specnlation as' to the jause of the scherne, but it is thonght to put tbe roads in a position to better jontrol all the trade for theirown financia! benefit. These roads are the great 3oal feeders to the upper lakes, ports ind territory beyond, and it is possible theie is something on between them and the Ohio coal roads which have tignred out a conibination. From the north comes word that the Ann Arbor is apt to pass into the conrol of the Pennsylvania, the idea of the big system being to run throngh ;rains from the seaboard to Minneapolis nd St. Paul. This inclndes a line into Detroit, and will give Ímpetus to the :umors that C. N. Haskell and the old Detroit & Lima folk, now building a :oad out of Toledo, are going to sell it :o the Pennsylvania.
