In Italy, Sardinia has the largest share of lines, having about 1200 miles; and in Germany, after Austria and Prussia, the largest share belongs to Bavaria, which has 1050. Saxony has 400 miles; Würtemberg, 195.

The distance between stations on lines of Continental telegraph is from ten to twelve miles on the average, and the number of them is about 3800.

In France the use of the electric telegraph has rapidly increased within the last few years. In 1851, the number of despatches transmitted was 9014, which produced 76,723 francs. In 1858, there were 463,973 despatches transmitted, producing 3,516,634 francs. During the last four years, that is to say, since all the chief towns in France have been in electric communication with Paris, and consequently with each other, there have been sent by private individuals 1,492,420 despatches, which have produced 12,528,591 francs. Out of the 97,728 despatches exchanged during the last three months of 1858, 23,728 were with Paris, and 15,409 with the thirty most important towns of France. These 15,409 despatches are divided, as to their object or nature, as follows:—Private and family affairs, 3102; journals, 523; commerce and manufactures, 6132; Bourse affairs, 5253; sundry affairs, 399.

In Australia, the electric telegraph is in constant use, affording a remunerating revenue, and the amount of business has forced on the government the necessity of additional wires.

Cuba has six hundred miles of wire in operation. Messages can be transmitted only in Spanish, and the closest surveillance is maintained by the government officials over all despatches offered for transmission. From the fact that no less than a dozen errors occurred in a dispatch transmitted by a Boston gentleman from Cardenas to Havana, we judge that the telegraphic apparatus, invented by our liberty-loving American, Professor House, rebels at such petty tyranny.

Several hundred miles of electric telegraph have been constructed in Mexico; but the unfortunate condition of the country for the last few years has precluded the possibility of maintaining it in working order, and it has, like everything else in the land of Monteznma, gone to decay.

The English and Dutch governments have come to an understanding upon a system of cables which will unite India and Australia, and eventually be extended to China. The arrangements between the governments are:—That the Indian and Imperial governments shall connect India with Singapore; that the Dutch government shall connect Singapore with the southeast point of Java; that the Australian governments shall connect their continent with Java. The cable for the Singapore-Java section was to have been laid during the last month; the Indian-Singapore section is to be laid this spring; and the connection with Australia will, it is believed, be completed in the course of next year.

The Red Sea and India Telegraph Company have announced the arrangements under which they are prepared to transmit messages for the public between Alexandria and Aden. Messages for Australia and China will be forwarded by post from Aden. It is considered probable that a direct communication with Alexandria will be established through Constantinople in the course of a few weeks, and then the news from India will reach London in ten or eleven days.

A late European steamer brings a report that two Russian engineers have proceeded to Pekin, China, to make preparations for a telegraphic connection between that place and the Russian territory.

There is reason to believe that arrangements will soon be made at St. Petersburg, through private companies and government subsidies, for completing the line of telegraph from Novgorod to the mouth of the Amoor, and thence across the straits to Russian America. In the mean time, a company has already been formed and incorporated in Canada, under the name of the Transmundane Telegraphic Company, which will afford important aid in continuing the proposed line through British America. The plan is, to carry the wires from the mouth of the Amoor across Behring's Strait, to and through Russian and British America. From Victoria a branch will be extended to San Francisco, and another to Canada. The line from San Francisco to Missouri is under way, and Mr. Collins, who is engaged in the Russian and Canadian enterprise, thinks that by the time it is in operation he shall have extended his line to San Francisco.
