27 beds, especially those interspersed with many rocky patches giving' foothold to luxuriant animal and plant life. The less mixed the sands of the chank-bed are with islands of coral and sponge life the less infected with Clioiie are the shells. Again, on beds regularly fished year after year the percentage of wormed shells is always low, and the shells of regular size. On beds seldom fished, the proportion of large and badly infected shells is always very high, and remains so till a thorough weeding out of the old shells has taken place. Tuticorin chanks are noted for their solidity, weight and hardness. Samples of loo shells containing average numbers of all sizes above 2f inches diameter have been repeatedly weighed and in all cases the weight exceeded 90 lbs. per 100 shells, the actual average of all lots being 93 lbs. Shells between 2^ and 2^ inches diameter weigh 54 lbs. to the 100 shells. The chank godowns are large rooms divided into a number of temporary divisions or bins to accommodate the various- grades of shells. Cleaning is left to nature which here takes the form of innumerable fly-maggots. These eat out the contents of the shells, windows being thoughtfully provided in the godowns for the entry of the parent flies. The odour evolved from the heaps of shells " is twin to that of pearl-oysters when being rotted ;" the local golf links come within 100 yards of the godowns and at one hole there is occasional complaint that the spicy breeze is somewhat rank in flavour. Previous to 19 10, the season's catch was advertised and sold yearly by tender to the highest bidder. In some years (i885 to 1891) the shells were put up to public auction, but this method led to abuse— the rich men buying off competition — and the old system of calling for offers by sealed tender was reverted to. In 19 10 a contract was made for a three -years with a Dacca firm of chank-merchants and as term this modification in the manner of disposing of the shells has proved of advantage both to the buyers and to Govern- ment, it is probable that, whenever possible, this system will be followed in future. The form of advertisement used in calling for tenders is given in the appendix.
