This particular quote from the third letter of De Crevecoeur's "Letters From An American Farmer" highlights the beginning of the laws and the establishment of laws within America and by the new American people.
"The laws, the indulgent laws, protect them as they arrive, stamping on them the symbol of adoption...This is the great operation daily performed by our laws. From whence proceed these laws? From our government. Whence the government? It is derived from the original genius and strong desire of the people ratified and confirmed by the crown. This is the great chain which links us all."
I believe the contemporary example and vision of this within America today is the United States Government. Congress, the Senate and the Supreme Court protect the American citizens that live within the borders of the United States. The United States government along with the courts uphold the rights of the American people and continue to protect the constitution ensuring that nothing damages or changes what they consider to be the "correct" way America should be.
Furthermore within the third letter, De Crevecoeur's also quotes "Here they rank as citizens." This highlights the fact that any citizen of America is protected by the Government, and when these letters were written those coming across from Europe would be classed as "citizens" and therefore automatically protected by the laws already and first governments established by the already settled Americans.
