many people imagine, and there are many ways of effecting 

 the operation. It is, however, always best to secure the ser- 

 vices of a good bricklayer who has had experience in setting 

 the different kinds of boilers, as they for the most part require 

 different treatment. Many a boiler has been condemned 

 through its being badly set, and the work being indifferently 

 carried out. There is another important point in connection with 

 boilers, i.e., they should be kept clean, and the flues free from 

 soot and dust, which not only greatly impedes the di'aught but 

 diminishes the heating power. Care should also be used in 

 stoking the fire, for a good deal of fuel may be wasted by 

 injudicious management, more especially as some kinds of 

 boilers do not take as much fuel as others. The man in 

 charge, if he takes a proper interest in his work, will however 

 soon become acquainted with the requirements of the different 

 boilers under his management. 



Hot-water boilers are now made of numerous shapes and 

 patterns, and as most cultivators have some predilection in 

 this matter, we leave them to make their own selection. There 

 are, however, many things to be thought of before deciding 

 this question. If the locality is such as to render it imprac- 

 ticable to dig far down into the ground before reaching water, 

 or to prevent a drain from being put below the boiler, then 

 the upright form of boiler is neither suitable nor safe ; for in 

 cases of flood during winter, the water may rise and put out 

 the fire, unless the stoke-hole is made water-tight, which is 

 usually a troublesome and expensive process. We, however, 

 by no means depreciate boilers of this type. Then we have 

 cannon boilers, tubular boilers, common saddle boilers, termi- 

 nal saddle boilers, tubular arched saddle boilers, double L 

 saddle boilers, Gold Medal boilers, improved tubular boilers, 

 Cornish boilers, cruciform boilers, duplex compensating boilers, 

 and boilers that require no setting, the makers of each and all
