TO POSTMASTERS. 
Many of the Postmasters throughout the Union 
do not seem to know that letters on Post-office 
business go free. It is only necessary to mail the 
letter unsealed, and write outside upon it “ P. 0. 
Business,” with the name of the Postmaster, and 
where mailed. For example, if a paper has a 
wrong direction, or it he refused, or anything of 
the kind takes place, by following the above 
directions, we can be informed of the facts without 
taxing us with postage. Postmasters ought, in all 
cases, to make themselves acquainted with their 
privileges. We trust that those unacquainted with 
the law will excuse this paragraph, as we have 
frequently had to pay postage on their letters, when 
they could have gone free. 
TO PRESERVE GRAPES. 
Take a well-bound cask, from which the head is 
to be removed, and place at the bottom a good layer of 
fine saw-dust or bran. On this place a layer of grapes, 
then bran and grapes alternately, until the cask is 
full, taking care that there is sufficient bran between 
each layer of grapes to prevent their touching each 
other. Put on the head, which is to be cemented, 
and the grapes will keep well for a year. When 
used, in order to restore their freshness, cut the 
stalk of each hunch, and place it in wine, as 
flowers are placed in water.
