[32] Suppose “an American vessel employed to take in negroes
      at some point on this coast.  There is no American man-of-war
      here to obtain intelligence.  What risk does she run of being
      searched?  But suppose that there is a man-of-war in port.  What
      is to secure the master of the merchantman against her [the
      man-of-war’s commander’s knowing all about his [the
      merchant-man’s] intention, or suspecting it in time to be upon
      him [the merchant-man] before he shall have run a league on
      his way to Texas?” Consul Trist to Commander Spence:  House
      Doc., 27 Cong. 1 sess.  No. 34, p. 41.]

 [33] A typical set of instructions was on the following plan: 
      1.  You are charged with the protection of legitimate commerce.
      2.  While the United States wishes to suppress the slave-trade,
      she will not admit a Right of Search by foreign vessels. 3. 
      You are to arrest slavers. 4.  You are to allow in no case an
      exercise of the Right of Search or any great interruption of
      legitimate commerce.—­To Commodore Perry, March 30, 1843:
