In the Fourth Class were those whose property did not fall below 25,000 lbs.

They also formed twenty centuries; their only arms were a spear and a javelin. The Fifth Class was larger, it formed thirty centuries. They carried slings and stones, and they included the supernumeraries, the horn-blowers, and the trumpeters, who formed three centuries. This Fifth Class was assessed at 11,000 lbs.

The rest of the population whose property fell below this were formed into one century and were exempt from military service. After thus regulating the equipment and distribution of the infantry, he rearranged the cavalry. He enrolled from amongst the principal men of the State twelve centuries.

In the same way he made six other centuries (though only three had been formed by Romulus) under the same names under which the first had been inaugurated. For the purchase of the horse, 10,000 lbs. were assigned them from the public treasury; whilst for its keep certain widows were assessed to pay 2000 lbs. each, annually. The burden of all these expenses was shifted from the poor on to the rich.

Then additional privileges were conferred. The former kings had maintained the constitution as handed down by Romulus, viz., manhood suffrage in which all alike possessed the same weight and enjoyed the same rights. Servius introduced a graduation; so that whilst no one was ostensibly deprived of his vote, all the voting power was in the hands of the principal men of the State.

The knights were first summoned to record their vote, then the eighty centuries of the infantry of the First Class; if their votes were divided, which seldom happened, it was arranged for the Second Class to be summoned; very seldom did the voting extend to the lowest Class.
