If the fish could be turned directly into the soil such a use might not be exposed to severe condemnation, although it is to be deprecated because it represents a serious misuse of valuable food. But, as a rule, this cannot be conducted with the essential promptitude for obvious reasons. Then the farmer suffers a heavy loss. Vigilant gulls and other birds having a well-defined penchant for fish diet raid the land to enjoy a Gargantuan feast with the minimum of effort on their part. The birds will even follow a train, or road wagons, bearing a manurial consignment of their food, for miles from the point of landing and then, after it has been dumped, will swoop down to gorge themselves to the full. In many instances a farmer has been known to lose at least 50 per cent. of his purchase in this manner. He may essay alert and effective measures to combat the birds’ attacks, but he will find it an unequal contest. In one instance, which came before my notice, the insatiable birds, catching sight of one or two open trucks laden with a freshly-landed catch _en route_ to the land, attacked the wagons so vigorously as to cause a very perceptible shrinkage in the load before it reached its destination. Another farmer, who had been persuaded to buy two or three truckloads of freshly-landed fish just because it was cheap, subsequently expressed his doubt as to whether he had driven a good bargain after all. The birds attacked the field over which the loads were distributed in such overwhelming numbers as to prompt the opinion that the field really contained more gulls than fish! So, after all, it is extremely questionable whether the purchase of a bumper catch for use as a fertilizer is really such a bargain as it may appear from a cursory reflection. In our large cities and towns the treatment of fish offal and surplus supplies drawn from the markets, stores, and retail shops, as well as the hotels, restaurants, and clubs, for industrial exploitation, should present no difficulty whatever. It is an offal apart and a noisome one. Its susceptibility to rapid decomposition and the emission of obnoxious odours during the process demand its prompt removal. It cannot be handled with other refuse owing to its offensiveness. Consequently the system of special collection by vehicles of the closed tank type has become the general practice. In this manner the disconcerting factor pertaining to the utilization of organic waste--effective segregation at the source--is assured.
