and the withdrawal of restrictions by Act of Parliament as to the
amount of sulphur present in the gas, the Company have very
seldom exceeded 30 grains in 100 cubic feet of gas during the
twelve months ended 31st March, 1907; the amount has fluctuated
between 22 and 27 grains, as will be seen from the curve which
I have constructed from the daily testings (Table 3), and the
average for the whole period was 24.6 grains. In Table 1 will be
seen the monthly averages of the sulphur impurity calculated from
the daily testings.
1 still note the somewhat remarkable relation to which 1
referred in my last report (Report of Council for the year ended
31st March, 1906, p. 163) between the amount of sulphur and the
illuminating power, and a distinct tendency towards an inverse
ratio between the two, as will be seen from a comparison of the
two curves in Table 3.
There has been no sulphuretted hydrogen in the gas during
the year ended 31st March, 1907.

This has rarely been less than a pressure equal to a column
of two inches of water, that is to say, more than
one inch above the statutory minimum; daily
observations have been made and duly reported.

The only legislation relating to the Wandsworth and Putney
Gas Company during the year ended 31st March,
1907, has been the passing of the Gas Companies
(Removal of Sulphur Restrictions) Act, 1906, which came into
force in July last, and to which I have already alluded above
under the heading "Sulphur." I have also made two reports on
this Act, one when it was in the Bill stage on January 10th, 1906,
and one on December 13th, 1906, some time after the passing of
the Act. The main points to be rioted in connection with the gas
testing and to which I have previously called attention are (1) the
continuance of the testing for sulphur impurities other than sulphuretted
hydrogen, (2) testing the illuminating power with flat
flame burner, (3) testing the calorific power of the gas, '(4) extension
by one hour in advance of the usual times of testing under
the Gas Works Clauses Act, 1871. At present the Council do not
propose to carry out (2) and (3), but the Act enables them to make
these tests at any time.
