After the naval and military objects are considered, a research could be made for the two great Roman roads that led to Cydamis, the present Gadam; a town, I am led to believe, of the utmost importance to travellers in the interior, as being the resort of numerous trading caravans.

“The site of the celebrated altars of the Philaeni would form a satisfactory point; for though they appear no longer to have existed in the time of Strabo, their situation might perhaps be placed by approximation.

“Enquiries might be made respecting the Silphium, a famous shrub which must have existed in abundance, as sugar was made from it; though others report that it bore benzoin and assafoetida; – that marked on the ancient coins, bears a strong resemblance to the large apncynum which grows on most parts of this coast.
