Matsudaira Boodzen No Kami to Robert H. Pruyn, April 19, 1863
Japanese ministers to Mr. Pruyn
We have to inform your excellency that the British minister, by letter of the 6th instant, has fully acquainted us with a demand his government instructed him to make, stating that a decisive answer is required within twenty days from the date of that letter.
It is desirable, however, that an extension be granted, as the letter, under present circumstances, cannot be answered soon.
We therefore request you to mediate for the obtainment of an extension of the limit as above stated. From the treaty such great friendship may be expected; and also, because we experienced your friendly feeling on more than one occasion.
The government of foreign affairs, Muragaki Awadli No Kami and Takemoto Hayato No Kami, under our instructions, will fully inform you of all the circumstances; and we now ask you, taking this into due consideration, for your friendly offices in this matter.
His Excellency Robert H. Pruyn, Minister Resident of the United States of America, &c., &c.
