have nearly seventy feet of piping, and, after the gas has been lit an hour it is nice and hot all round. The whole affair can be made and fitted by any gasfitter for a little over three pounds, and I can only say, in conclusion, that it works admirably, and the only trouble I have met with is, to see that the cistern is supplied with water about once a week, and to turn the gas on at night and off again in the morning.”

One of the most important of these, for the amateur who has but one or two houses, is Riddell’s slow combustion boiler, which consists of furnace and water jacket, constructed of iron, and needing no brick-setting, although, in common with all other boilers, it should be sheltered from the weather by means of a shed, or in one end of the plant house screened off from the rest. This is a very economical boiler, quick and powerful, and well adapted for pipes of small bore. It is manufactured by Messrs. Riddell, 155, Cheapside.
