two in the evening
Having occupied two days in this way , we turned our attention to other duties : the cultivation of a wheat , barley and maize field , the management of the ostrich 's eggs , and the taming of the captives . As agriculture was , though the least to our taste , the most important of these several duties , we set about it first . The animals drew the plough , but the digging and hoeing taxed our powers of endurance to the utmost . We worked two hours in the morning and two in the evening . Fully did we realize the words of Scripture : ` In the sweat of thy face shalt thou eat bread . ' In the interval we devoted our attention to the ostrich . But our efforts on behalf of his education seemed all in vain .
