Supplies for the hospitals.—On Saturday a car will be attached to the mail train on the Central railroad, to bring, free of charge, from all depots and turnouts between this point and Louisa C. H., any contributions of food or other articles for the sick and wounded soldiers in our hospitals. This practice will be continued daily, if the people of the country prove sufficiently liberal and patriotic to make it necessary.
