also been made to drive the bottom heading from a point in the cutting south of the tunnel, 480 ft. from the shaft and this had been driven about 40 ft. This heading is in decomposed granite and was so far offering no difficulties although rather heavily watered. The gullet in the approach cutting, also in decomposed granite, had reached the tunnel face and the heading into the tunnel was on the point of being started. Since December these headings had been extended and by the last mail were advancing about six feet per day.
Mr. Eves has been recommended to put down another shaft 270 ft. deep, 1,350 ft. from the north face. This will expedite the work by at least three months and will also facilitate the egress of spoil and ingress of building material which will be a very serious question when all the faces inside the tunnel are at work.
It is evident, however, that if the work is to be completed in say 3 to 3½ years an extremely large labour force will be required, the supply and transport of building material also must be carefully organized on a very large and complete scale, as when the tunnel work is in full operation, work will be going on at 16 faces at the same time and these must all be served by the two headings. Much of course depends on the nature of the material to be met with; a great deal will no doubt be composed granite with boulders but, there is little doubt that solid granite rock will also be found.
In view of what has been said, it is evident that the construction of the tunnel is a large and serious problem and will keep a large organizing staff busy besides necessitating the importation of an unusual amount of suitable labour. The most suitable would, as we have said, be probably drawn from the mining population in the vicinity of the Kaiping mines in North China, and this must be organized. The English tunnel foremen sent out have not turned out very satisfactorily and in various matters difficulties have occurred which are not infrequently...
