The above table shows that practically the same results were obtained 

 from the different cuttings of seed whether the variety was an early or 

 late one. 



Third Maryland report. 



Work of Verification — Potatoes. Again the effort has been made to 

 verify the experimental results regarding the best form of potato for plant- 

 ing, by growing potatoes by the acre, under ordinary farm conditions, 

 comparing the different forms of tuber for seed and with all the facts 

 accurately observed and recorded. Although the early crop was a failure 

 and the late one far from satisfactory, the comparative record was obtained 

 and this again substantially verifies the conclusions of former experiments. 

 These field tests or verifications, proved that the most profitable form of 

 seed for potato planting, in the average season, is the whole potato of egg 

 size, in every hill, and that in some seasons, a much larger potato uncut, is 

 profitable." 



"The arrangement of rows and distance of planting, same as in 1889, 

 rows 2f feet apart and hills 2 feet apart in the row. Early potatoes were 

 planted March 26, and late potatoes June 24; in both cases, the seed 

 was carefully dropped in the furrow, by hand, covered with a light plow, 

 and then smoothly harrowed. On the early acre there were 48 rows, each 

 363 feet long, and on the late acre, 60 rows, each 200 feet long. As here-, 

 tofore, the rows were planted in sets of fours alternating across the field 

 the four forms of seed compared, viz: 



" A, a whole potato about ten ounces in weight. 



" B, a whole potato about the size of a hen's egg. 



" C, the usual cutting, piece of medium tuber, with two to four eyes. 



" D, a piece cut from medium tuber, and having one eye on it; one 

 whole tuber or one piece, as described, in each hill. 



" From these records, the product per acre has been computed from the 

 four different forms of seed planted, and these three varieties and the 

 results follow."
