“ Under our system of government, administered in its true spirit, there never can be a conflict. It is pernicious to the best interests to build on this foundation, for 'a house divided against itself will fall.'

The State owes the same obedience and observance to the same power. The Constitution enters and pervades our system everywhere. ”
