but, aside from other objections, he shrewdly suspected that Mexico had by this time lost control of the territory. In December, 1847, Dr. Mora, who succeeded Murphy, proposed on his own responsibility a sale of California to England, arguing that by our endeavor to purchase it the United States had confessed we had no claim there; but Palmerston, though evidently tempted again, merely decided that any authorized communication on the subject should receive the attention justly due to its importance, and soon the treaty of peace put an end to the matter. No "substantial advantage" had seemed to come within reach.[1]
Nor had even a satisfactory pretext for intervention been found. McLane had urged our government to give none, and in particular to avoid all infringement upon the rights of neutrals.[2] The policy of our blockade was extremely liberal. British mail packets were exempt from its restrictions, and they were permitted to embark specie and land quicksilver at Vera Cruz and Tampico. During the blockade of Mazatlán British subjects were treated with such consideration that our courtesy was formally acknowledged, and it was admitted that Scott "invariably" guarded their interests in the sphere of his operations. Our opening the ports to all nations, establishing a low tariff, and endeavoring to protect commercial relations with the interior were boons that foreign powers had no reason to expect, and British traders appreciated our attitude. By December, 1847, the merchants of London were distinctly opposed to intervention; and when the Duc de de Broglie demanded in astonishment why England had viewed our military operations with such indifference, he was told that Mexico in the hands of the United States would be of far more value in regard to commerce and investments than ever before. At the same time persons of less narrow views hoped to see that country regenerated through us.[3]
On the other hand embarrassments of the most serious character stood in the way of interposition. As the Globe said, the project of annexing Texas had afforded better grounds, yet England had looked aghast before the prospect of losses and risks involved in a collision with this country. So had she done in the case of Oregon; and the advantages of remaining at peace with the United States were still obvious. There
