The second process is of the conventional milling character, the flake being ground to an extremely fine consistency. During this process the skin and all other inedible portions are removed. It may be mentioned that by turning the tubers into flake, slightly diseased potatoes, which would be useless for the table, or which could only be wastefully adapted to such a purpose, may be used without imperilling the purity of the product in any way, and with the minimum of loss. The flaking process presents an absolutely sterilized flour, the diseased portions being removed during milling. All offal is carefully collected to be treated separately. It has pronounced food value for cattle, and, consequently, is converted into a meal. The production of 1 ton of farina yields about 300 lb. of offal, worth about £20--$100--a ton. The farina itself is of very fine consistency, yellowish-white in colour, appetizing in appearance, of pleasing aroma, the distinctive fragrance of the potato being scarcely discernible, and, if preserved from the damp, may be kept indefinitely. It is not imperative that the flake should be milled immediately. In the former condition the potato may be safely stored in bags in a dry place after the manner of grain. It is not even essential to turn it into farina at all. In the flake form it constitutes an excellent base for the other industries to which it may be applied. It may be distilled for the extraction of the alcohol, excellent whisky, as is doubtless well known, being made from the potato, while large quantities of British brandies are produced from the starch which, by treatment with weak sulphuric acid, is converted into glucose, which is then fermented. Thus, it will be seen, the flake really represents the starting-point for numerous applications, each of which has its individual commercial possibilities. The outstanding advantage accruing from the conversion of the potato into flake is that it enables the product to be kept indefinitely, without suffering the slightest deterioration, and without any waste being incurred. I have seen samples which have been stored for seven years, and which to-day are in every way as good as flake fresh from the machine. In setting forth the composition of the succulent tuber I referred to the item waste, which in the analysis given stands at 1.4 per cent. This is the ultimate residue from certain operations, but is not common to all, as, for instance, in the production of farina, where everything of a solid nature is utilized. But in some branches of industrial use there results a residue for which, at present, no attractive purpose has been found, although there are hopes that even this insignificant fraction will ultimately prove capable of profitable exploitation.
