We have before us a map prepared by Mr. Thomas Ferguson of rhe I. M. Castoms to the convenient scale of one ud Shanghai.: pie one mile, the principal waterws}
With the exception of the Coast Line Lower Whangpoo River—taken from Admiralty chart: hove Map is the result of an origi survey made with the P of a 'Hodogesph,' an instrument which automatically records courses and distances, and consequently the shape of waterways passed over, Asa check, most of the creeks were pussed over twice, in opposite directions, thus i uracy not much below that of a to-graphical survey,"
'The area covered may be taken, ape proximately, as 20 miles Sout', Eas? and West of Shanghai City and 12 miles on the North.
Commencing in the North-v st corner, we find the tow: ith its fine creek running Sout! riy.
On the West we lave the Szekongko (Four Waters) some 4 miles above Wons-clu and in the South-west the well-known, hills, Fung Wangsan," with the city of Sungkiang som: 7 miles to the South.
wore tht a ranning survey has been inde of the upper reach-s of the Huing-River, but that the actual locations of the banks have no: been determine explains the somewhat meagre ow'line of some 3) miles of the River Huangpu above Shanghai.
Leaving the river at Dongk'o, however, Fergus has run a survey of the ervek leading to the town of Chuensha on the Yangtz, only 7 miles West of the: Kiutow Lightship. This creek, passing through Tsoup'u, is accredited by Mr. Ferguson with having 42 bridges of ample height with only 3 classed as doubtful.
On the west side of the Huangpu the most important waterway is, of course, the Siccawei Creek leading to' Fungwangsan, the creek running from there to Four Waters, a favourite route for returning from the hills, being also shown in deta.
Tu the hands of x keen up-country tripper the outline map now under rev might be filled in with a 1+t of usefal information, and on this account alone we consider that Mr. Ferguson has rendered signal service to the pleasure-seeking community of Shanghai.
The instrument by the aid of which Mr. Ferguson has prepared this map, was the subject of a very interesting ead by him before the Society of Engineers ud Architects, not long ago, and the map now before us certainly shows what excellent results can be obtained by its use, results which can only be regarded as standing testimony to the skill and ingenuity of its inventor.
It is a matter of regret that Mr. Fergusom's removal to Suxchow prevented him from Glting more detail into the map now published, but we slvill hope to hear more from him anon, as we understand the Hodograph is not lying idle at Soochow, but is being employes on a survey of the very interesting neighbourhood round about.
We congratulate th author of the map on the results of his efforts to produce such an acceptable outline of the waterways round Shanghai.
