other words, to induce the public to think that they are receiving a well
prepared or freshly made article. Preservatives in milk have been largely
used by people who mix separated milk with pure milk to prevent its quickly
turning sour, which would almost certainly occur as the machine-skimmed
product is a day older than the milk with which it is mixed. Consequently
if a preservative were not added, the mixed article would turn sour soon
after delivery to the customer.
In this case we see that the use of a preservative may prevent
the detection of a fraud so long as the proportion of fat in the mixture
is not less than the low figure laid down in the Board of Agriculture's
regulations.
WATER SUPPLY.
The water supply of Islington, about which no complaint has of recent
years been received at the Public Health Department, continues to be of
a high quality.
It is obtained from the New River and from water from the River Lea.
It is partly the product also of wells sunk in the chalk and green sand
formations which are situate at Broad Mead, Amwell End, Amwell
Hill, Amwell Marsh, Rye Common, Hoddesden, Broxbourne, Turnford,
Cheshunt, Whitewebbs, Hoe Lane, Alma Road, Hadley Road (construction
in progress) Highfield, Edmonton, Betstile, Tottenham Park, Tottenham Hale,
and Campsbourne, from which the water is brought into the aqueduct known
as the New River and thence into numerous reservoirs.
The supply in the borough, as pointed out last year, is entirely on
the constant system and there is delivered daily 33.58 per head of the
population.
The latest available return is that for 1903-1904, taken from the 34th
annual report of the Local Government Board, and gives the following
particulars respecting the water from the New River.
