304 Coffee Culture on tbe Soutbern Coast of Cbiapas, 



of three yards on each side, fifty- three additional trees may be planted, 

 making a total, with the sixty-nine already counted, of one hundred 

 and twenty-two ; and when the trees are planted three yards apart on 

 one side and two on the other, a cuerda will contain eighty-three addi- 

 tional trees, which, added to the original one hundred and five, give 

 a total of one hundred and eighty-eight. 



C. Yield of each Cuerda. Considering the average crop per year of 

 each plant to be two pounds of coffee, each cuerda, when the plants are 

 four yards apart on each side, will yield seventy-eight pounds a year; 

 one hundred and four pounds if the plants are three yards apart on 

 one side and four on the other; one hundred and thirty-eight, if they 

 are three yards apart on each side ; and two hundred and eight pounds 

 if they are two yards on one side and three on the other. 



.When the additional tree is planted in the middle of each square, 

 or parallelogram, the yield of each cuerda will be one hundred and 

 thirty-two pounds, if the trees are planted four yards apart on each side ; 

 one hundred and eighty pounds if they are planted four yards apart on 

 one side and three on the other; two hundred and ten pounds, when 

 they are three and a half yards apart on one side and three on the other ; 

 two hundred and forty-four pounds, when they are planted three yards 

 apart on each side ; and three hundred and seventy-six pounds when they 

 are planted two yards apart on one side and three on the other. 



It must be observed, however, that the yield of each tree depends 

 also on the nature of the soil, on the climate, on the degree of moisture, 

 and the other circumstances which have been already enumerated, in- 

 cluding the distance apart at which the trees are planted, for if they 

 are planted too close together, so that their roots interlace, the yield 

 will be less. 



D. Area Required by each Tree. If the trees are planted two yards 

 apart, from plant to plant, and three yards from furrow to furrow, 

 each tree will have an area of six yards square ; if planted three yards 

 apart, from plant to plant and from furrow to furrow, each plant will 

 have an area of nine yards square ; if planted three and a half yards 

 apart on each side, of twelve and a quarter yards; and of sixteen 

 yards square, if planted four yards apart on each side. 



When an additional tree is planted in the middle of each square, or 

 parallelogram, each plant will have an area of ground nearly eight 

 yards square ; if the trees are planted four yards apart on each side, of 

 a little more than six ; when planted three yards apart on one side and 

 four on the other, of nearly five yards square; when planted three and 

 a half yards apart on one side and three on the other; of four and a 

 quarter yards square, when planted three yards apart on each side ; and 

 of nearly one and three quarter yards when planted three yards apart 

 on one side and two on the other.
