cooking, more especially when applied to small domestic establishments. For instance, the ingenious machinery necessary for carrying it out, requires cooks perfectly conversant with its use; and if the gas, when the cooking operations are finished, be not turned off, there will be a large increase in the cost of cooking, instead of the economy which it has been supposed to bring. For large establishments, such as some of the immense London warehouses, where a large number of young men have to be catered for daily, it may be well adapted, as it is just possible that a slight increase in the supply of gas necessary for a couple of joints, may serve equally to cook a dozen dishes.
