Stores Depot has been the general receiving, distributing and clearing house for all supplies and equipment used by the brigade, and it is estimated that between 20,000 and 30,000 different types of articles and appliances have been carried in its spacious premises.

Provision of this organization was recognized as an imperative necessity at the very inception of the Corps. Its procedure has been from the start greatly assisted by the fact that the Aviation Department of the Imperial Munitions Board has acted as purchasing agent, and has always placed its unique facilities at the service of the R.A.F. and secured for the latter the very best possible terms and deliveries procurable. In order to reduce as far as possible the labor imposed upon the Imperial Munitions Board, the requirements of each unit for a definite length of time were estimated, grouped and submitted as one request. It will be understood that these requirements covered all needs from socks to propellers. This procedure is termed “provisioning.”

Purchased material, being received at Stores Depot, is subject to a minute inspection, and no payments are made by the Munitions Board until notification has been received from the inspection department that the articles received are in classification and quantity exactly what has been ordered. If this centralizing of receiving work should be considered in any way unnecessary, it has only be to pointed out that the receipt of purchased material is thereby enormously simplified, and the duty of inspection is unified in one specially qualified organization.

It is easily seen that without extreme care Stores Depot might have accumulated an enormous quantity of innumerable articles, quantities far beyond actual requirements of the various units for whom they were purchased. In consequence, the practice has invariably been to compile a schedule covering the needs for six months of each branch of the service, and confine the stocks carried to these amounts.

The amount of work discharged by Stores Depot has been probably not thoroughly appreciated, even by the various branches of the brigade. Records show an average receipt per week for the last year of some 250 shipments, or between thirty or forty a day. These shipments range from one case to seventy or eighty cases each, while from the commencement of Stores to November, 1918, there have been placed with the Aviation Department of the Imperial Munitions Board some 9,000 requisitions, each of which represents an average of ten different types of articles, each requisition in turn has been covered by from one to ten orders placed by the Munitions Board, while every order has been covered by from one up to as high as one hundred invoices.

The responsibility of Stores Depot has involved not only receipt and distribution of all supplies required by the brigade, but also the maintenance of a form of record which will enable the government auditors to trace the entire history of any article which has passed through this organization, from the date of the order given for its purchase up to the point at which it has reached the end of its serviceable life and been written off.

It will, of course, be understood that supplies have been sent to the various wings only upon a request being made by the latter, and it is furthermore necessary that the type and amount of the equipment which is being asked for coincide with the provision Stores Depot are authorized to make, and the rate of consumption which is laid down as being proper for the particular service involved. If, on the other hand, any purchase is necessary of articles not carried as standard, special authority is required to be granted before action is taken.

The move to Texas of a section of the Corps in October, 1917, and the return of that section to Canada in April, 1918, threw additional responsibility on Stores Depot organization, and shipments which involved as many as twenty carloads per day were frequently sent out, the total value of articles thus forwarded being over $2,000,000. It was also of extreme importance that on the return of the Aerial Gunnery School to its permanent quarters at Beamsville, this unit should find itself equipped with the involved and often highly technical scheduled supplies required for its special duty, and it is to be recorded that this provision was admirably foreseen and supplied.

In the Stores Depot, as well as in all other units, excellent service has been rendered by lady civilian subordinates, and in October no less than 184 were on the strength of this unit. There was required, of course, the special training of those hitherto unskilled in these particular duties, but the result has amply justified the trouble taken. Over and above the civilian subordinates, there were on the strength 17 officers and 217 other ranks. All have contributed to a notable degree to the success of the work of other units, which without a constant dependable supply of necessary equipment would have been soon rendered ineffective.
