the clouds. Draining marfhy ground is a neceflary 

 bufinefs, and, as I have before faid, expofes the 

 workmen to hazard from the nature of the moifture,

 fudden tranfitions from heat to cold. 



Intemperance is particularly dangerous under fuch 

 circumftances. It is highly proper, and even ne- 

 ceflary, that thofe who perform fuch kind of labour 

 fhould have a fufficient, and even liberal allowance, 

 in point of diet; butexcefs of any kind, in fpiritu- 

 ous liquors efpecially, tends to weaken the ftomach, 

 and in confequence thereof, the whole vital fyftem, 

 and to render the body more liable to receive con- 

 tagion of every kind. This is not a caution founded 

 merely on theory or general principles, but a fact in 



medicine eftabJifhed beyond all doubt. Another 



caution very neceflary to be attended to is, that 

 none fhould go to fuch kind of labour in the morn-
