The laying of underground wires is, however, developing fast, but it is usually cheaper to keep the wires overhead, and in the present state of electrical science the effectiveness of a telephone wire is reduced when laid underground. In the Postmaster-General's Report for 1906 he deplored the differences into which he was forced with landowners, and “with those valuable associations whose care it is to preserve the natural beauty of the country. In the case of Hindhead I am glad to say that, thanks to the consideration shown by the Directors of the London and South-Western Railway, I was able to take the poles by another route.” It is pleasant to find consideration for the beauty of the country influencing the policy of the Post Office. The Postmaster-General went on to say that “means of overcoming the present difficulties are urgently required; for it is most unsatisfactory that important towns should go for years with inadequate trunk telephone facilities because it has not been possible to overcome some difficulty of wayleave many miles away.” This was written before the Telegraph Construction Act of 1908 was passed, but even with increased powers the Department experiences great opposition from local authorities and others to the erection of overhead wires, and the wayleave getter's task is still difficult in many districts. Another of the works carried out by the Engineer's Department is the establishment of a system of synchronisation of clocks by means of ingenious automatic appliances, and in this matter the Post Office has given a lead to the nation. At no distant date, if the example of the Post Office is followed, we may be spared the experience which frequently occurs in a London street, of finding a difference of time in almost every clock we pass. The Post Office clocks are like Wordsworth's cloud, they move together if they move at all. (_b_) _Stores and Factories_
