June 3, 1848, "Mr. Drayton submitted the following resolution; which was considered, by unanimous consent, and agreed to:-- "_Resolved_, That the Vice-President be requested to have the flag of the United States first erected by the American army upon the palace in the capital of Mexico, and now here presented, deposited for safe-keeping in the Department of State of the United States."--Page 370, Journal of the Senate 1847-48. The union of the United States flag at present contains thirty-one stars. (See Fig. 3, Plate III.) We have, in the preceding pages, offered many reasons for concluding that the devices in the flag, its colors, and the manner in which they were combined, originated in some circumstance directly connected with the history of the colonies, or in some practice which prevailed in the mother country. Particularly was this the case in the adoption of the emblem of union from the mother country. This leads us to make a few remarks as to the prominence given to the color blue in the reports on the adoption of the device for a Great Seal of the United States, and in its being the ground of the uniform of the United States. We have previously stated that its adoption was due to other circumstances directly, than its being typical of the virtues of perseverance, vigilance, and justice, though indirectly this meaning was involved in its adoption. First, blue was a favorite color in the colonies, as is proved by the fact of its being the uniform of the South Carolina troops in 1775. For we have seen that Colonel Moultrie caused a large blue flag to be made, with a crescent in one corner, to be uniform with the troops; and by the fact that the pine-tree flag of New England was a blue field, containing in the upper canton, next the staff, a St. George's cross on a white ground, and a pine-tree represented in the upper square formed by the cross. A reason for this color being a favorite in New England, may perhaps be found in the circumstance, that, in 1679, when the banner of the league and covenant was raised in Scotland, it was a red flag, the borders of which were edged with blue.[63] Borders of different color from the body of the flag, or from the shield of the coat of arms, are in heraldry, a common distinction, and as such was doubtless applied by the Covenanters (blue being the color of the field of the banner of Scotland, as we have seen), to indicate by whom this red flag was raised, and thus the blue color became identified with the league and covenant. After the defeat of Bothwell's Bridge, many of those people fled to the colonies, particularly to New England and New Jersey. [63] Walter Scott's Old Mortality, vol. ii. p. 116.
