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.

For some time it restricted its operations to constructing and maintaining railway telegraphs and was not commercially successful.
After about five years great improvements were made in the working of the telegraphs and the industry began to make progress.
