cultivator and averaged a trifle more than three feet apart. 

 There were on the half-acre 32 rows, 210 feet long. 



To see what the potatoes would say about the fertilizer 

 whether it furnished enough plant food or not, I tried the 

 following experiment : the first five rows were left with 

 the fertilizer alone, the next five rows were manured in 

 the hill with horse manure in addition to the fertilizer ; 

 the next five were left with the fertilizer and the next 

 manured in the hill with the horse manure at the rate of 

 four cords per acre, and the same way through the piece 

 for thirty rows, the odd two rows were left with nothing. 

 To also satisfy myself in a measure about the quantity of 

 seed needed, I planted in the first ten rows whole large 

 potatoes in hills, one in a hill three feet apart in the row, 

 the next ten rows were planted with the same sized pota- 

 toes cut in halves, the next ten rows (with the exception 

 of one row, which was planted with one eye in a place) 

 were planted with the same sized potatoes cut in quarters, 

 the halves were planted eighteen inches apart, the quar- 

 ters twelve inches apart, and the one-eye pieces about ten 

 inches apart in the row, so the amount of seed per acre 

 was about the same They were struck with blight about 

 the first of August, and I dug enough soon after, before 

 they began to rot very badly, to ascertain the amount of 

 yield in the different rows. You will see that the final 

 yield after they had about done rotting fell far short of the 

 promised amount. The experiment throughout was con- 

 ducted in a very careful manner and the measurements 

 and weights as near as I could make them. I herewith 

 give you the results as I found them. 



Where the whole potatoes were planted on fertilizer 

 alone the yield was 310 pounds per row, or 330 2-3 bushels 

 per acre. On fertilizer and manure in the hill the yield 

 was 155 pounds per row or 165 1-3 bushels per acre (rotted 

 badly).
