A correspondent of the Garden says:

"Anthracite is extensively used and very highly spoken of by Mr. B. S. Williams, of Hol-loway. He prefers it to coke, because it is more powerful, and, therefore, really more economical. This fuel is said to produce the best results when a small, bright, thin fire is kept in the furnaces, distributed fairly over the bars. By adopting this plan combustion is more complete than when the furnace is choked up with a great bulk of fuel - a mistake often made by inexperienced stokers. Of course, when making up the fires for the last time at night it is requisite to add a considerable quantity of fuel, but at all other times, and especially when the heat has declined and requires to be quickly got up, a thin, bright fire is absolutely necessary. I am convinced that bad stoking is to blame for half the failures with boilers that are attributed to other causes. The kind of boiler that finds most favor with Mr. Williams is the fluedsaddle, known as the gold medal boiler, which appears to be simple and powerful".
