A little eastward of the Lowest Pool of Solomon, near its commencement, the aqueduct receives a con- siderable accession of water, beyond that which it de- rives from the pools themselves, or through the pipe from the Fountain Sealed, which, commencing at the fountain, skirts them on the north-east.
