The milk traffic has in some cases been rapid, almost sudden, in its growth. Though the Great Western is at present the greatest of the milk lines, it brought very little into London prior to the year 1865. In the month of August in that year it brought 23,474 gallons, and in the month of October following the quantity had increased to 103,214 gallons. Last year the total quantity delivered in London by this single railway was 1,514,836 gallons, or an average of 30,000 gallons a week. The largest proportion of this milk was brought from beyond Swindon in Wiltshire, about 100 miles from London; but considerable quantities were also brought from the vale of Gloucester and from Somerset. The London and Southwestern also is a great milk-carrying line, having brought as much as 1,480,272 gallons to London last year, or an average of 28,000 gallons a week. The Great Eastern brought nearly the same quantity, 1,322,429 gallons, or an average of about 25,400 gallons a week. The London and Northwestern ranks next, having brought 643,432 gallons in 1867; then the Great Northern, 455,916 gallons; the Southeastern, 435,668 gallons; and the Brighton, 419,254 gallons. The total quantity of milk delivered in London by railway last year was 6,309,446 gallons, or above 120,000 gallons a week. Yet this traffic, large though it may appear, is as yet but in its infancy, and in the course of a few more years it will be found very largely increased, according as facilities are provided for its accommodation and transit.
