material except wool, worsted, and silk, in the piece or in any other
form, a duty, as a military contribution, of 30 per cent _ad valorem_.

deficiencies, leakage, breakage, or damage proved to have actually

goods are warehoused.

Third. The period named in the eighth of said regulations during which
the goods may remain in warehouse before the payment of duties is
extended from thirty to ninety days, and within said period of ninety
days any portion of the said goods on which the duties, as a military
contribution, have been paid may be taken, after such payment, from the
warehouse and entered free of any further duty at any other port or
ports of Mexico in our military possession, the facts of the case, with
a particular description of said goods and a statement that the duties
thereon have been paid, being certified by the proper officer of the
