declivity becomes less precipitous. My estimate 
concerning the p g which 
this stair descends brings it very near to 1500 
feet: ac lower part it gradually runs off or passes 
“intoa pavement, constructed of the most regular 
slabs of Basaltes collected in the environs. This 
stair has not been preserved complete to the 
present period; the tracesare frequently broken 
or obterated, by currents of water descending 
with impetuosity in accidental excavations, and 
the present road deviates in many places: but 
at intervals 3 or 4, and sometimes io and more
