The total chaining amounted to 32,854.52 chains or 410.68 linear miles, and the angular work was checked by 27 azimuths.
The following Districts and Sub-Districts fell within the area traversed :--
a. Sub-Districts Luk Keng, Kuk Po, Nam Yeuk and Hing Chun of the
Sha Tau Kok District.
b. Sub-Districts Kau Yeuk, Luk Yeuk and Hap Wo of the Kau Lung
District.
r. The whole of the Tung Hoi District.
d. Portions of Lan Tao Island near Tung Chung and Mui Wo.
e. All the cultivated islands in Mirs Bays.
3. One Traverse Surveyor was sent back to India in June, 1901, and by the end of 1902 the remaining man had finished the rest of the Territory.
He was employed in office for a couple of months and returned to India in March, 1903.
In 1902, 2,431 new Stations were put down, of which 1,860 were marked with clay cylinders. The chaining amounted to 27,133.10 chains or 339.16 linear miles, and 6 azimuths were observed.
The cultivated area of New Kowloon, comprising Districts 1, 2, 3, 4, 5 and 9, which have been resurveyed or a larger scale, was retraversed as all the old traverse stations, originally marked with wooden pegs, had been destroyed by the villagers.
Four Demarcation Districts near Sha Tau Kok were also retraversed as a resurvey was necessary on a larger scale.
A traverse survey was also made of the cultivated area of old Kowloon, viz., that portion lying between the old boundary fence to the north and Yau Ma Ti and Hung Hom to the south.

5. Five-inch theodolites of the EVEREST pattern were used for the angular work; and for the measurements of all distances we used 2 chains of unequal lengths, one being the ordinary GUNTER'S chain of 100 links — 22 yards, and the
other a GUNTER'S chain minus 7 links.
The results obtained from these independent measurements were compared on the spot by means of a conversion table, and in cases of discrepancy, the distances were immediately rechained.
To ensure the accuracy of all chaining, each Surveyor's squad, in addition to the ordinary working chains, was supplied with 2 standard chains. All chains before being made over to the Surveyors, were tested on the standard laid down at the Headquarter camp, by means of the steel standard tape, and the spare chains were sent in once a fortnight to be tested on the standard. The Surveyors had orders to test their working chains daily in the field againt their spare standard chains.
6. The traverses were connected with the Stations of the Trigonometrical Survey wherever possible, but only the following connections were utilised for the comparison of the direct distances by the Trigonometrical Survey and the Traverse Survey-Kowloon City Station, White Head Station, Sha Tau Kok Station and Tung Chung Station on Lan Tao Island.
