The Telegraph in California.

SAN FRANCISCO, Oct. 31st.

TO THE EDITOR OP THE TELEGRAPHER.

I SEND you a few telegraphic items, which are likely to be of some interest to your readers.

The Western Union Company will, on the second day of November, remove from its old quarters in Montgomery Street to a fine new office in California Street, above Montgomery, and opposite the California market.

The Atlantic and Pacific States Telegraph Company occupy five rooms a block nearer the Board of Brokers, and directly on the corner of California and Montgomery Streets, which is much the best location of the two. The A. and P. States Telegraph Company already has 2 two wires in operation as far as Sacramento, via San Jose, Stockton and Way Stations, 187 miles in all, and by the first of December its wires will be completed and in operation to Virginia city. This Company is constructing a superior line, using 35 poles to the mile, No. 9 iron wire, galvanized, and the BROOKS Patent Paraffine Insulator. The BROOKS Insulator gives great satisfaction here. It is considered decidedly superior to any other for use in this climate, when, during the wet season, a perfect insulation is essential to a decent working of the wires. A system of double transmission, invented by Mr. S. D. FIELD, has just been introduced on these lines, between San Francisco and Sacramento, with the most satisfactory results.

It is rumored that the Western Union Company, having found it impracticable to work the MORSE system on their long overland lines during the winter season, on account of defective insulation, has decided to introduce the Combination Instruments between San Francisco and Virginia city.

The activity of the opposition Company has spurred the Western Union Company to an unwonted degree of activity, including the erection of fifty miles of new line on the old United States Company's poles, for the purpose of ascertaining the practicability of working two wires on the same set of poles! Your readers may rely on the correctness of this last statement, as it is a quotation from the sworn affidavit of the W. U. Superintendent, in the case of the Western Union vs. the Atlantic and Pacific States Telegraph Company.

The tariff on the Western Union lines from this city to Sacramento has been reduced from one dollar to fifteen cents for ten words. Notwithstanding this the opposition are doing the larger part of the business at twenty-five cents for ten words.

The opposition Company have used in construction some twenty-six miles of the new American compound wire between Sacramento and Virginia city, and propose using some seventy miles additional of this wire on the same circuit.

The Central Pacific Railroad Company are erecting two first-class lines, of the same description as those of the Atlantic and Pacific States Company, along the line of their track, and have recently ordered two hundred miles of the compound wire for their lines. It is rumored that they, on the completion of their lines, propose to do a general dispatch business from here to the Eastern States.

The Fire Alarm and Police Telegraph of this city will soon be supplied with eight of the large sized magnet dial instruments, manufactured by EDMANDS & HAMBLET, of Boston, Mass., for use on the Police Telegraph Line. Seventeen of these instruments are now in use on private lines, of from one to thirty miles in length, in and about the city.
