The subject of compounds is one of the most difficult of the matters relating to correct literary composition. The difficulty arises from the fact that usage, especially in the matter of the presence or absence of the hyphen, is not clearly settled. Progressive tendencies are at work and there is great difference of usage, even among authorities of the first rank, with regard to many compounds in common use.

An attempt is made to show first the general character of the problems involved. Then follows a discussion of the general principles of compounding. The general rules for the formation of compounds are stated and briefly discussed. The various components of compounds are fully analyzed and tabulated. The best modern usage in the matter of the employment of the hyphen is set forth in a series of rules. The whole is concluded by practical advice to the compositor as to the use of the rules in the actual work of the office.
