The other ministries with the largest outgoings were the ministry of war (the expenditure of which rose from 254 millions in 1895 to over 30 millions in 1995), the ministry of marine (103/4 millions in 1895, over 123/4 millionsin 1905), the ministry of public works (with an expenditure in 1905 of over 20 millions, 10 millions of which was assigned to posts, telegraphs and telephones) and the ministry of public instruction, fine arts and public worship, the expenditure on education having risen from 73/4 millions in 1895 to 93/4 millions in 1905.
The postal services and the telegraphs are administered by the federal government.
In the aerial or overground system of land telegraphs the use of copper wire has become very general.
The instruments used for land telegraphs on this system are of two types - " sounders," which indicate by sound, and " recorders," which record the signals.
In Hughes's instrument almost perfect accuracy and certainty have been attained; and in actual practice it has proved to be decidedly superior to all previous type-printing telegraphs, not only in speed and accuracy, but in less liability to mechanical derangement from wear and tear and from accident.
