Cunningham's Ancient Geography of India c12.6

c12.6

Hwen Thsang describes the *yojana* as equal to 8 krosas, or kos, of 500 dhanus, or "bow lengths" of 4 cubits each. The yojana would therefore be only 24,000 feet, or a little more than 4½ miles. But in all the Hindu books the yojana is reckoned at 4 krosas, either of 1000 or of 2000 dhanus or bow lengths. The former value agrees with the length of the yojana as stated by Hwen Thsang, and the latter is the double measure of about 9 miles, which gives the common kos of 2¼ miles that is in use in many parts of India at the present day.
