[34] We have no idea of the frightful character of pagan slavery. The worst form which negro slavery ever took never approached it. The following story will give our readers some idea of it. Cato, the censor, wrote a treatise, very little read or known, called _De Re Rustica_, treating of farming operations. In this he gives directions concerning the economical management of slaves, and among other things tells how wine for their winter consumption was to be prepared. "Put into a cask ten amphoræ of sweet wine, two amphoræ of sour vinegar, and as much wine boiled down by two-thirds. Add fifty amphoræ of pure water. Mix all together with a stick three times a day for five consecutive days. After this add sixty-four amphoræ of stale salt and water." [35] See St. George Mivart, _Genesis of Species_, p. 282. The whole chapter (xii.) on Theology and Evolution is well worth careful study. CHAPTER IV. _THE ELECTION OF MATTHIAS._ "They prayed, and said, Thou, Lord, which knowest the hearts of all men, shew of these two the one whom Thou hast chosen, to take the place in this ministry and apostleship from which Judas fell away, that he might go to his own place. And they gave lots for them; and the lot fell upon Matthias; and he was numbered with the eleven apostles."--ACTS i. 24-6. We have selected the incident of this apostolic election as the central point round which to group the events of the ten days' expectation which elapsed between the Ascension and Pentecost. But though this election is a most important fact, in itself and in the principles involved therein, yet there are numerous other circumstances in this waiting time which demand and will amply repay our thoughtful attention.
