The Convention was to meet on the 1st of September, at Monterey; but it did not get regularly organized until the 4th of that month, when Dr. Robert Semple, of the Sonoma district, was chosen president. The proportion of the native Californian members to the American was about equal to that of the population. Among the members was Captain John Sutter, the pioneer settler of California, General Vallejo and Antonio Pico, who had both been distinguished men in California, before the conquest. The body, as a whole, commanded respect, as being dignified and intellectual. The Declaration of Rights was the first measure adopted by the Convention. Its sections being general and liberal in their character, were nearly all adopted by a unanimous vote. The clause prohibiting the existence of slavery was the unanimous sentiment of the Convention. The Constitution will be found in another part of this work, and we will not here recapitulate its provisions. It combines the best features of the Constitutions of the States east of the Rocky Mountains, and is in most respects similar to that of the State of New York. The most exciting questions discussed were, a clause prohibiting the entrance of free people of color into the State, the boundary line, and the great seal of the State. The first, the clause prohibiting the entrance of free people of color into the State, passed first reading, but was subsequently rejected by a large majority. The question of suffrage occasioned some discussion, widely differing opinions being entertained by the members. An article was adopted by the Convention, excluding Indians and negroes, with their descendants, from the privilege of voting; but it was subsequently modified by a proviso, which gave the Legislature power of admitting Indians, or the descendants of Indians to the right of suffrage by a two-thirds concurrent vote. Under this provision, some of the most wealthy and influential Californians are excluded from voting until permitted by the Legislature. The boundary question, which came up towards the close of the Convention, was the most exciting theme. The point of dispute was the eastern boundary line. The Pacific formed the natural boundary on the west; the parallel of 42 degrees, the boundary on the north, and the Mexican line, run in conformity with the treaty of Guadalupe Hidalgo, the boundary on the south. The discussion, reconsideration and voting upon the various propositions occupied nearly two days. Finally, the line detailed in the Constitution was adopted.
