reclaimed. These salvaged materials are taken from the refuse when the dustmen empty the
bin into the refuse vehicle. The materials are then placed in a basket suspended at the rear
of the vehicle.
On arrival at the depot, the rags and bottles are sorted into grades. Metals are graded
and paper bundled ; they are then disposed of to contractors. No cleansing of any kind is
done, but four men are employed in grading the materials. For reclaiming saleable waste the
dustmen receive 25 per cent, of the nett profit made on the sale of the materials.
The foregoing information is not submitted as a complete account of " waste " materials

Examination
of milk.
Milk and Dairies (Consolidation) Act, 1915, and Tuberculosis Order, 1925.
Since 1st July, 1908, it has been the practice for the Council to take samples of
liquid milk arriving by road or rail from the provinces for biological examination
to ascertain the extent to which the milk supply on its arrival in London is infected
with tuberculosis. In the event of a positive result, the medical officer of the county
of origin is notified, when arrangements are made by him for the farm from which
the milk originated to be visited and the herd examined.

On account of the decision arrived at in 1934 that no useful purpose would be
served by sampling milk brought into London in tanks on account of the practical
impossibility of tracing the farm of origin, these figures relate to samples taken from
churns only.
The milk subject to sampling in 1935 was received from 29 counties. As a
result of consequential investigations 119 cows were dealt with under the Tuberculosis
Order, 1925; in some additional cases it was reported that the owners had taken
action before the medical officer of the county concerned made his inspection.
The number of cows dealt with under the Tuberculosis Order, 1925, shows a
marked increase over previous years. This increase may be put down to greater
vigilance on the part of county authorities to whom notifications have been sent,
as in verv few cases has it been found imnossible to trace the source of infection.
Institutions
under the
control of th<
Oounoil.
The cows kept at institutions under the control of the Council have been
inspected quarterly by the Council's veterinary surgeons, and samples of the milk
have been taken at least twice during the year. The results of sampling and of
veterinary inspection were as follows:—
