Special Difficulties,

The construction of a railway in China presents some difficulties not) commen in other countries. We have all read of the troubles en- countered by the early lines, in getting through or past the many graves scattered over the country. A podus operandi has now bean developed which greatly simplifies this though it still is something of a problem. The walled cities alko girders
