In the meantime all loose or inferior bunches are raked down through the openings in the grading tables and received in sweatboxes below, to be either further dried or to be stemmed and graded at once. In packing several grades of layer raisins, the grading of the bunches should be made at this table. No great choice in selecting the bunches should be left to the packer, as his time should alone be occupied with the packing of his box. The best way is to have differently colored scales for number one and number two layers, and when taking them out of the sweatbox assort them at once by placing them in different trays. The graders can never be too careful. No moist raisins, no small ones, no red and poor raisins, should ever be allowed among a better quality. They will lower the grade of the whole box, while the good quality of high-grade raisins will not raise the grade of a generally poor box. Thus, while the many good raisins in a poor box are not paid for according to their value, the few poor raisins which will be accidentally or carelessly smuggled in a good box will lower the value of the whole. Few packers will sufficiently understand this, which is really the principle of all good packing, and which should be scrupulously adhered to. Even inferior size berries, if otherwise ever so good, should be carefully clipped from the large-berried bunches. It is astonishing how quickly the buyer will notice a few small berries, and how readily he will ignore the value of the largest raisins in the box.
