 room between the outside of the descending rim of the 

 cover and the vertical side of the steam-rim to contain 

 all the water that can be forced upwards between them 

 by the steam, there is little danger of any part of this 

 water being blown out of the steam-rim by the steam 

 when it makes its escape under the rim of the cover. 



Of the Manner in which Kitchen Boikrs and Stewpans 

 may be constructed so as to be rendered useful in 

 cooking with Steam. 



If a common kitchen boiler be furnished with a steam-

 down into it, the steam in the boiler will be effectually 

 confined, and may in various ways be usefully employed
