 (plans and sections). 

 Salt-works existed at one time or another in 209 localities in Galicia, 

 and counted ^85 shafts and 276 wells ; of these a great number are 

 abandoned. Particulars as to the yield, &c. of each are given in tables. 

 Their chemical composition is compared with that of the Alpine salt- 

 works and with sea water, the percentage of salts being grajihically 

 represented in a table. E. B. T.

 Floods do great damage to the district, and especially to the town ; 

 they obstruct the sewage-works and foul the wells. It is proposed to 

 construct a series of embankments, taking advantage of the low terraces 

 of old river-gravels. The flood-waters wiU then be confined to the E. 

 side of the vaUey, and they can only aflect the town by lateral percola- 

 tion through the gravel. AV. T.
