Besides the irrigation figures it is necessary to record for each outlet its chainage, size of barrel[29] and commanded culturable area. In the case of a distributary which has been working for years, and on which the outlets are undergoing few alterations, it may be suitable to record the above items in a separate “outlet register,” and to give in the irrigation register a reference to the page of the outlet register. But even in such a case alterations will have to be made from time to time in the outlet register and there is great danger of its becoming spoilt, imperfect or unintelligible. In the case of a distributary on which the outlets are undergoing frequent changes, the items under consideration should be shown crop by crop, and also the material of the outlet--wood or masonry--and the width and mean height of the barrel. In no other way can the working of the outlet be properly followed and understood. It is probable that this procedure is the best in every case, _i.e._, even when the alterations made are not frequent. By arranging the register as shown in table III. the repetition of the entries, when they undergo no alteration, is avoided, only dots having to be made. [29] The sizes of the outlets should be measured by the suboverseer and some checked by the Subdivisional Officer and the correct sectional area, as actually built, entered. The specimen shows only two outlets on a page, and covers five years, but three outlets can easily be shown on a large page, and the period can be seven years. If there are more than three outlets in the village, the lowest part of the page shows the total of the page instead of the total of the village, and the other outlets are shown on the next page, the grand total for the village coming at the foot.
