"Special regard must be paid to agriculture."

... "Fifth:  Special regard must be paid to agriculture. Although it hath been mentioned in the fifth place, unquestionably it precedeth the others. Agriculture is highly developed in foreign lands, however in Persia it hath so far been grievously neglected. It is hoped that His Majesty the Sháh—may God assist him by His grace—will turn his attention to this vital and important matter."
