The nutritive ratio is i : 8"5, whilst the nutritive value is 68. As 

 sugar, pectose, gums, &c., take the place of starch in these peas, the 

 starch equivalent cannot be calculated in the usual way because sugar 

 and the other substances contain less carbon, and have consequently 

 less nutritive value. 



Algerian specimens from the igoo Exhibirion have been analysed 

 by M. Balland : — 



One fine pod weighed 22'65 gr. , and contained fourteen seeds weigh- 

 ing 2'65 gr. 



The weight of the pods, may vary from 8-6 gr. to 24 gr., the seeds 

 accounting for 0*2 gr. to 2*4 gr. The latter only represent 10 per 

 cent, of the weight of the pods. 



In Tunis the natives feed on a mixture of ^'^hcat and carob. This 

 mixture, of which there was a sample at the " Concours agricole de 

 Paris" of 1Q02, had the appearance of a coarse powder. 



M. Balland has made the following analyses of whole pods which 

 contained seeds. 



It will be seen that the proportion of sugar varies within fairly 

 wide limits, the other elements I'emaining about the same : —

When the carob bean or carob fruit is green it contains a big 

 proportion of tannin, and is very astringent. In Algeria, when in this 

 state, it is used for tanning the finest Moroccan leathers. 



When mature the pods are brown in colour and fall spontaneously. 

 In order to preserve them they must be dried ; if they are heaped before- 

 hand they will be impaired by fermentation and turned blackish. 



England and France import fairly large quantities. Pigs, horses, 

 and also milch cows and other animals will eat them; cows are said 

 to give more milk as a result. During the Peninsular War the mules
