It would seem wise to reduce the loss upon second-class mail matter, at least to the extent of preventing a deficit in the total operations of the Post-Office.
The deficit every year in the Post-Office Department is largely caused by the low rate of postage of 1 cent a pound charged on second-class mail matter, which includes not only newspapers, but magazines and miscellaneous periodicals.

The effect of that law is emphatically shown in the following table giving amounts of second-class mail (periodical literature) carried by the Post Office Department at various dates.

The above list will hopefully provide you with a few useful examples demonstrating the appropriate usage of "class mail" in a variety of sentences. We hope that you will now be able to make sentences using this group of words.
