There was some advance in public opinion between 1850 and 1860, but, on the whole, adverse influences prevailed and little was achieved. The effects of separate political development and of divided interest were deeply rooted. Leaders of opinion in the various provinces, and even men of the same province, refused to join hands for any great national purpose. Party conflict absorbed {15} their best energies. To this period, however, belongs the spadework which laid the foundations of the future structure. The British American League held its various meetings and adopted its resolutions. But the League was mainly a party counterblast to the Annexation Manifesto of 1849 and soon disappeared. To this period, too, belong the writings of able advocates of union like P. S. Hamilton of Halifax and J. C. Taché of Quebec, whose treatises possess even to-day more than historical value. Another notable contribution to the subject was the lecture by Alexander Morris entitled _Nova Britannia_, first delivered at Montreal in 1858 and afterwards published. Yet such propaganda aroused no perceptible enthusiasm. In Great Britain the whole question of colonial relations was in process of evolution, while her statesmen were doubtful, as ours were, of what the ultimate end would be. That a full conception of colonial self-government had not yet dawned is shown by these words, written in 1852 by Earl Grey to Lord John Russell: '_It is obvious that if the colonies are not to become independent states, some kind of authority must be exercised by the Government at home._'
