ordance with which, if we regard the proportion of the first
levy to the whole men capable of bearing arms specified for
the Bellovaci as holding good generally, the number of the Belgae
capable of bearing arms would amount to 500,000 and the whole
population accordingly to at least 2,000,000. The Helvetii with
the adjoining peoples numbered before their migration 336,000; if
we assume that they were at that time already dislodged from
the right bank of the Rhine, their territory may be estimated at nearly
1350 square miles. Whether the serfs are included in this, we can
the less determine, as we do not know the form which slavery
assumed amongst the Celts; what Caesar relates (i. 4) as to
the slaves, clients, and debtors of Orgetorix tells rather in favour
of, than against, their being included.

That, moreover, every such attempt to make up by combinations for
the statistical basis, in which ancient history is especially
deficient, must be received with due caution, will be at once
apprehended by the intelligent reader, while he will not absolutely
reject it on that account.

12. "In the interior of Transalpine Gaul on the Rhine," says
Scrofa in Varro, De R. R. i. 7, 8, "when I commanded there, I
traversed some districts, where neither the vine nor the olive nor
the fruit-tree appears, where they manure the fields with white
Pit-chalk, where they have neither rock--nor sea-salt, but make use
of the saline ashes of certain burnt wood instead of salt." This
description refers probably to the period before Caesar and to
the eastern districts of the old province, such as the country of
the Allobroges; subsequently Pliny (H. N. xvii. 6, 42 seq.) describes
at length the Gallo-Britannic manuring with marl.

13. "The Gallic oxen especially are of good repute in Italy, for
field labour forsooth; whereas the Ligurian are good for nothing."
(Varro, De R. R. ii. 5, 9). Here, no doubt, Cisalpine Gaul is
referred to, but the cattle-husbandry there doubtless goes back to
the Celtic epoch. Plautus already mentions the "Gallic ponies"
(-Gallici canterii-, Aul. iii. 5. 21). "It is not every race that
is suited for the business of herdsmen; neither the Bastulians nor
the Turdulians" (both in Andalusia) "are fit for it; the Celts are
the best, especially as respects beasts for riding and burden
(-iumenta-)" (Varro, De R. R. ii. 10, 4).

14. We are led to this conclusion by the designation of
the trading or "round" as contra
