28 JOURNAL. 



June. AVe began this day to make ufe of Dodor Irving*s 



apparatus for dilHllIng f refli water from the fea : repeated 

 trials gave us the molt fatisfa<9:ory proof of its utility: the 

 water produced from it was perfedly free from fait, and 

 wholefome, being ufed for boiling the fhip's provifions ; 

 which convenience would alone be a defirable objed in all 

 voyages, independent of the benefit of fo ufeful a refource 

 in cafe of diftrefs for water. The quantity produced every 

 day varied from accidental circumltances, but was gene- 

 rally from thirty-four to forty gallons, without any great 

 addition of fuel. Twice indeed the quantity produced 

 was only twenty-three gallons on each diftillation j this 

 amounts to more than a quart for each man, which, 

 though not a plentiful allowance, is much more than 

 what is neceflTary for fubiiftence. In cafes of real neceffity * 

 I have no reafon to doubt that a much greater quantity 

 might be produced without an inconvenient expence of 

 fuel.
