A foreman, on receipt of a regularly numbered and authorized production order or sub─production order, is thereby authorized to make requisition for such stock and material as may be necessary to use in the execution of the order. This he will do by the use of the _Requisition_ shown in Fig. 23, entering the order number and date, and specifying the quantities and descriptions of the articles required. Ordinarily each requisition will contain but one article or class of articles. At the bottom of the requisition, the foreman will enter the name of his department and his own signature. These requisition blanks are made up in pads (the form shown in Fig. 23), of white paper alternating with tinted paper on which is the _Invoice_ form shown in Fig. 24. This latter form has its ruling and other principal features identical with the form of the requisition, so that by the use of carbon paper the foreman makes a duplicate on the Invoice blank, of the order number and date, the articles required, the name of his department, and his own signature. [Illustration: Fig. 25. Returned Material Card.] When the Storekeeper issues the articles, he first enters upon the requisition blank the date issued, and then passes it to his assistant, who notes the issue on the _Stock Ledger Card_, and then places it on file. The Storekeeper will enter on the invoice the rate and value of the articles issued, and the date of issue, and will sign it under the foreman's signature. He will send it, with the articles issued, to the foreman, who will in turn make it a part of his report of material used. When the work on an order is completed, such serviceable stock and material as may remain will be returned to the Storekeeper, together with a _Returned Material Card_ of the form shown in Fig. 25. The Storekeeper will enter upon it the value of the material returned, credit it to the department from which it came, and sign the receipt in the lower left─hand corner. The card will then be returned to the foreman as his authority for deducting the amount from the material account in the order in question.
