The quality of the instruction given was not of the best; only those taught who could do little else. The girls are said to have been much better scholars than the boys, whose minds ran rather upon military matters. Often their play was military drill, and listening to war stories their chief intellectual exercise.[601] Some rare and marvellous text-books again saw the light during the war. Old books that had been stored away for two generations were brought out for use. Webster's "blue back" Speller was the chief reliance, and when the old copies wore out, a revised southern edition of the book was issued. Smith's Grammar was expurgated of its New Englandism and made a patriotic impression by its exercises. Davies's old Arithmetics were used, and several new mathematical works appeared. Very large editions of Confederate text-books were published in Mobile, and especially in Richmond; South Carolina, North Carolina, and Georgia also furnished Confederate text-books to Alabama. Mobile furnished Mississippi.[602] I have seen a small geography which had crude maps of all the countries, including the Confederate States, but omitting the United States. A few lines of text recognized the existence of the latter country. Another geography was evidently intended to teach patriotism and pugnacity, to judge from its contents. Here are some extracts from W. B. Moore's Primary Geography: "In a few years the northern states, finding their climate too cold for the negroes to be profitable, sold them to the people living farther south. Then the northern states passed laws to forbid any person owning slaves in their borders. Then the northern people began to preach, to lecture, and to write about the sin of slavery. The money for which they had sold their slaves was now partly spent in trying to persuade the southern states to send their slaves back to Africa.... The people [of the North] are ingenious and enterprising, and are noted for their tact in 'driving a bargain.' They are refined and intelligent on all subjects but that of negro slavery; on this they are mad.... This [the Confederacy] is a great country! The Yankees thought to starve us out when they sent their ships to guard our seaport towns. But we have learned to make many things; to do without others. "Q. Has the Confederacy any commerce? "A. A fine inland commerce, and bids fair, sometime, to have a grand commerce on the high seas. "Q. What is the present drawback to our trade? "A. An unlawful blockade by the miserable and hellish Yankee nation."[603]
