Charges of greatest Efficacy for Artillery at Sea . 277 
In consequence of these principles, care ought to be 
taken to fill the vat in twenty -four hours. In Burgundy 
the vintage is terminated in four or five days. Too long 
time would be attended with the disagreeable inconveni- 
ence of a successive series of fermentations, which, on 
that account alone, would be all imperfect ; a portion of 
the mass would be already fermented, while the fermen- 
tation would be scarcely begun in another. The wine 
thence resulting would then be a real mixture of several 
wines more or less fermented. The intelligent agricul- 
turist, therefore, anxious for the quality of his products, 
ought to determine the number of the vintagers according 
to the known capacity of his vat ; and when unexpected 
rain makes him suspend the labour of collecting the 
grapes, he ought to leave to ferment separately the juice 
of those already collected and placed in the vat, rather 
than run the hazard of exposing himself some days after 
to the danger of interrupting its movements and altering 
its nature by the addition of fresh and aqueous must.
