sent at the boring of an artesian well at Rivesaltes; the water was 
found, and spouted up abundantly. ‘They proceeded to the tubing, and 
to my friend, M. Bassal, who was with me—‘ This is a remarkable fact, 
posed of a hollow boring rod, formed of wrought iron tubes screwed 
end to end; the lower end of the hollow rod is armed with a perfora- 
bular rod, in order to form around it an annular space through which 
the water and the excavated material may rise up. The upper end ot

worked, the pump must be: first put in motion. — Through the interior 
of the tube a column of water is sent: down to the bottom of the bore- 
holes, which water, rising in the annular space between the exterior of 
the hollow boring rod and the sides of the bore-hole, creates an ascend- 
ing current which carries up the triturated soil: the boring tube is then 
worked like an ordinary boring rod; and as the material is acted upon
