If the quantities ordered prove too small, the deficiency can be made good by the matron with crackers, tea, canned meats, or meat essence, &c., in the pantry; it being best, if possible, to avoid any call upon the cook or the ship's kitchen for this purpose. If the quantities prove too large for one day, the saving can be used the next. Whether too large or too small, a proper modification can be readily made in the order to the cook for the remainder of the trip. The surgeon in charge will in this way be relieved of the necessity of giving further consideration to this department of administration, which, if not thus simplified, will be found to be a source of much trouble and anxiety, greatly withdrawing his attention from surgical and medical duties proper. Associated surgeons should be careful to make no demands for diet, inconsistent with this arrangement. Milk-punch is best made with cold water in the pantry. This and all other cold drinks can be made under the superintendence of the matron, without any call upon the cook. The cook should, however, be required to keep a supply, as large as convenient, of hot water, constantly ready to meet any demand from a surgeon or the matron. APPENDIX C. See page 97. _Copy of Letter to the Medical Director of the Army of the Potomac._ White House, Va., June 3, 1862. MY DEAR SIR:—There must be some frightful misunderstanding at the bottom of what is occurring here, in your department. It is obvious from the tenor of your telegraphic communications to me, that you are altogether wrongly informed about it. The Sanitary Commission, let me say at once, has not only obeyed every order, no matter how irregular or disrespectful the mode of its transmission, but has in good faith endeavored to carry out, at every point it could reach, what was judged to be _your intention_, supplying the absence or neglect of other agents on whom you appeared to depend, as it best could. Till night before last it made itself subordinate to the Surgeon-General of Pennsylvania, who assumed to act as your aid, and, under positive orders given by him in your name, it refrained from pursuing a plan previously approved by you, and by following which it is now obvious that a much greater and safer transport of the wounded would have occurred. From Sunday night to the present time, the Surgeon-General of Pennsylvania has not been seen here; a thousand wounded men have, in the mean time, arrived, and, as far as I am informed, not the slightest provision of any kind has been made for them under order from you, or by any one whom you have regarded as under your orders, except the Sanitary Commission. After waiting some hours yesterday morning for the Surgeon-General of Pennsylvania (who till then had been in charge of the railroad wharf) to act, finding men fainting in the sun ashore, I assumed the responsibility of taking
