where a few people boil the fish for the oil in earthen 

 chatties but throw azvay the soHd materials ; a small 

 battery of chatties was tried with considerable success, 

 but the chatties not infrequently break, resulting in some 

 loss. Next season experiments will be tried with small 

 metal chatties and a cheap lever press, so that persons 

 v«ith only Rs. lo or Rs. 20 may utilize surplus sardines to 

 advantage. 



13. From work at the station, I am able now to give 

 accurate data — for the late season only — as to outturn 

 and cost, and to show the big profits obtained. The 

 register kept shows the weight and cost of each parcel of 

 fish or guts, the amount of labour spent in producing 

 therefrom the oil and guano, the weight and cost of fuel 

 used, and the outturn in oil and guano. What is true, 

 however, of one season is not necessarily so of another ; 

 the fish dift^er largely in fat contents in different seasons, 

 and while in 1909 the very fattest were obtained in 

 March, those of March 19 10 were almost useless as 

 oil producers. Roughly speaking, 15 per cent of the 

 weioht of the raw fish can be obtained as crude oil from 

 September to February inclusive, and 20 per cent as 

 dry guano. This is for whole fish ; if only " guts," 

 which includes head, intestines, and a small part of the 

 tissues, are used, the oil is about or above 15 per cent 

 and the guano 18 or 19 percent. 



The figures for whole fish work out somethino- as
