2 SYSTEMATIC POMOLOGY 



572. Arch Duke (Fig:. 202).— The qualities which give Arch 

 Duke liigh place among commercial varieties 

 are: large size; handsome color, — a rich dark 

 purple with thick bloom ; and firmness of flesh 

 and skin, so that it keeps and ships well. The 

 plum of Arch Duke compared with that of 

 Grand Duke is nearly as large, with neck 

 thicker, the same color, bloom heavier, qual- 

 ity higher, flesh firmer, stone free, and season 

 earlier. All the tree characters, like those of 

 the fruit, are good. Arch Duke was raised by 

 Thomas Rivers, Sawbridgeworth, England, 

 and was sent out in 1883.

573. Gueii (Fig. 203) ranks among the first six plums in 

 eastern America. Its popularity is due to 



its being a money-maker, as few would care 

 to grow it in a home orchard. The quality 

 of the fruit is poor, but the trees bear early 

 and abundantly ; are large, vigorous, healthy, 

 and hardy; and the plums are hardly sur- 

 passed for shipping. The stone sometimes 

 clings rather tightly, and under other con- 

 ditions is wholly free. Gueii originated w4th 

 a Mr. Hagaman, Lansingburgh, New York, 

 about 1830.
