cut round the seal; rather than to break it, and tear the letter open.
In folding a letter let the breadth (from right to left) far exceed the height. A letter the least verging towards squareness looks very awkward. It is well to use a folding-stick (or ivory paper-knife) to press along the edges of the folds, and make them smooth and even. Take care in folding a letter to make all the creases exactly straight and even. If one is looser than another, or if there is the slightest widening out or narrowing in towards the edge of the turn-over, the letters will have a crooked, unsightly appearance. You may direct it before sealing; slipping your ruled paper under the back of the letter, that you may run no risk of writing the direction crooked. Begin the address rather nearer to the bottom than the top of the folded letter. Write the name of the person to whom you send it about the middle, and very clearly and distinctly. Then give the number and street on the next line a little nearer to the right. Then the town in large letters, and extending almost close to the extreme right. Just under the town, add the abbreviation of the name of the state—as, Pa. for Pennsylvania, N. Y. for New York. But if the letter is to go to New York city, put the words New York in full, written large. Much confusion is caused by this state and its metropolis having both the same name. It has been well suggested that the name of the state might be changed to Ontario—a beautiful change.
If the letter is to go to a provincial town, put the name of the county in which that town is situated, immediately over the designation of the state. We believe that throughout the union there are more than fifty towns called Washington. If your letter is for the city of Washington, direct for Washington, D. C.—these initials implying the District of Columbia.
