When the subject of casting howitzers, conformably to the British calibre, came to be more minutely and definitively discussed, difficulties with respect to the scarcity of materials, the danger of errors in the proportion, the want of a proper person to inspect the business, in a word, objections of different kinds were started; these, added to the facility of casting shells in America, determined me finally to substitute six inch howitzers of French calibre. Experience has proved, on a comparison of their effects with those of the larger sized howitzers, that the difference is trifling, and that the former will answer all the purposes of the latter, while their proportions render them more manageable, and economise ammunition. The French artillerists, enlightened by this discovery, have determined the reform of all their larger howitzers. Upon my arrival at Brest I found the whole of the articles agreed to be furnished for the first convoy were not yet arrived. In these circumstances I substituted some articles which I found in the magazine there, that there might not be any further loss of time, and that there should be the least possible interval between our sailing and the embarcation of the specie, which once commenced could not be kept secret in passing through a number of hands, and might be a temptation to enterprises on the part of the enemy. The same motive determined me not to shift the whole of the money into cases, which would have been more portable. This precaution became indispensable however with respect to two of the casks, that had suffered too much from the violent shaking on the road to be embarked in that condition, and although all the casks are double, I apprehend the most scrupulous care will be necessary in their debarcation and removal. I send herewith the Chevalier de l'Angle's receipt for the specie on board the frigate Resolve, the copy of the Treasurer's note at Brest, and invoices of the cargoes on board the Cibelle and the Olimpe. Besides these, the whole of the surgical instruments, drugs, and tin and wire for camp kettles, agreeably to the Board of War's estimate, are supplied upon the same footing as the other articles. The drugs and tin I expect in the brigantine Active. In addition to the list, I left a statement of the ulterior demands. These, in addition to the cargo expected by Gillon, and the invoices already cited, include the total of the supplies.
