92 BARILLA AND KELP. 



young people tell me the difference between barilla and 

 kelp? 



ESTHER. 



I fear not; but we must ask you to explain it. 



They are both, as you know, alkalis, and produce soda. 

 Barilla is the ash of the plant Sabola Soda, which is largely 

 cultivated upon the Mediterranean shore of Spain, in the vi- 

 cinity of Alicant.* Kelp is a production of Great Britain, 

 and consists of the ashes of sea-weeds, which are collected 

 upon many of the rocky coasts of Britain, particularly in the 

 Highlands, where it affords employment to a large popula- 

 tion. 



ESTHER. 



It is produced from a species of Tangle or Fucus, is it 

 not? 



Ulvse and Fuci. 



MRS. c. 

 There are four species which are principally used Fucus 



* As much as fifty-five per cent, of soda is contained in the ashes 

 of Salsola sativa, which grows in Sicily. (Lindley. )
