To the Senate of the United States:
I deem it proper to invite the attention of the Senate to the fact that with this day expires the limitation of time for the exchange of the ratifications of the treaty with Costa Rica of 2d July, 1860.
The minister of that Republic is disappointed in not having received the copy intended for exchange, and the period will lapse without the possibility of carrying out the provisions of the convention in this respect.
I submit, therefore, the expediency of the passage of a resolution authorizing the exchange of ratifications at such time as may be convenient, the limitations of the ninth article to the contrary notwithstanding.
