Parenthesis marks are used to enclose explanatory expressions that are not an essential part of the sentence; as,
The United States Department of Agriculture estimates that the receipts of cattle at the six leading markets (Chicago, St. Louis, Kansas City, South Omaha, St. Joseph, and Sioux City) from January 1 to August 1 of this year are 15 per cent less than they were in the corresponding period of last year.
Wrong.—Do not use parenthesis marks to cancel a word or a passage. A line should be drawn through a word that is wrong.
Bring to class five sentences that illustrate the correct use of parenthesis marks.
Exercise 195—The Hyphen (-)
The hyphen is used when a word has been divided. It is always used at the end of the line and never at the beginning.
When several short words are taken together to form one word, they are hyphenated; as,
a one-hundred-pound bag of coffee
As a rule, when two words taken together are each accented, they must be written with the hyphen. When only one is accented, no hyphen is used; as,
follow-up, first-class, self-reliant, railroad, steamship
