GOVERNMENT POLICY OF PLANT INTRODUCTION 41 



duction work, with which the name of Mr. Mark A. Carleton as its 

 pioneer will always be associated. 



The California Nursery Company, which soon after its intro- 

 duction secured cuttings of a seedless table grape called the Sul- 

 tanina rosea, has been propagating and selling cuttings to the public, 

 charging the highest prices yet paid for any of their grapes, and 

 the growers of the Thompson seedless variety are planting it as a 

 larger fruited and more attractive form for shipment to the eastern 

 market. This variety was found near a monastery near Padua, 

 Italy. 



I believe the mango industry has come to stay in Florida, Porto 

 Rico, Hawaii, and perhaps in California. The introduction of the 

 best East Indian varieties and their fruiting out has, I believe, 

 convinced those skeptics who were acquainted only with the tur- 

 pentine seedling varieties that we have in the East Indian mango 

 one of the most delicious and richest flavored fruits in the world. 

 The fancy fruit dealers have passed their verdict upon these East 

 Indian varieties and plantings on a commercial scale are being 

 made at the present time. The project has become of sufficient 

 importance to demand nearly the whole time and attention of a 

 special expert of the Office. 



While I am talking to you here today my assistant, Mr. R. A. 

 Young, is addressing the enthusiastic residents of the little town of 

 Brooksville, Florida, on the subject of the dasheen, which he has been 

 investigating for the last four years and which was first brought to 

 the attention of the public by the investigations of Mr. O. W. Barrett 

 while horticulturist in Porto Rico. There is no question about 

 the possibilities of this new root crop for the South which contains 

 ten per cent more protein and half again as much starch as the 

 potato. It can be grown where the potato does not do well, is a large 

 yielder, and produces its crop when there are no potatoes in the 

 local markets of the South except those shipped in from the North. 

 As a food plant it deserves to find a permanent place on our menus. 

 Several tons of seed tubers will be planted next year to furnish 

 distribution material to hundreds of experimenters who have applied 

 for material with which to test it on their own farms. 



The introduction of the wild peach of China, used there quite 

 generally as a stock for all stone fruits except the cherry, has at-
