he it was who first sent seeds to Europe. 

 The district is a long way north of 

 Bangkok, but so far as known all the 

 seeds found their way out of the coun- 

 try through that port. The American 

 supply came from London or Ghent. 



Now from Mississippi. 



Now the news comes from Pass Chris- 

 tian, Miss., that J. B. Adams & Sons 

 liave two plants bearing seed. Last year 

 the firm gathered about 300 seeds, which 

 they planted, and now have 275 young 

 plants in 2-inch pots. This year both 

 palms are bearing, and one of them has 

 thousands of seeds just turning brown. 

 When ripe some of this seed will bo 

 offered to the trade and the rest 

 jilanted. 



BLACK ROT ON DAHLIAS. 



I am sending you under separate 

 cover a few dahlias which ar5 diseased. 

 This infection of black streaks that 

 you will see along the stem will stunt 

 the plant and wilt the leaves. This is 

 <]uite troublesome and causes consider- 

 able loss of blooms. Is it a fungus or 

 insects? H. J. J. — Mo. 



I do not think insects have anything 

 to do with the trouble. This black stem 

 rot is a disease the cause of which we 

 .ire unable to understand. It is impos- 

 sible to tell exactly what causes this 

 and similar diseases, and the best means 

 of combating them is careful and clean 

 culture of the plants. 



I would advise destroying not only 

 the affected branch but also the tuber 

 from which the diseased shoot came. 

 This is the only safeguard against tlio 

 spreading of the disease to the rest of 

 the dahlia stock. 



It would also be a good plan to cliango 

 the planting ground for the dahlias 

 next season and, after giving their pres- 

 ent location a good dressing of air- 

 slaked lime, use the space for some other 

 crop for a year or two. M. P. 



NAMES OF TWO PLANTS. 



Under separate cover, I am sending 

 you a package containing two plants, 

 of which I wish to find out the names. 



C. F. P.— Kan. 



The name of the green and goUlon- 

 leaved shrub is Evonymus japonica 

 aureo-variegata, and the colored-leaved 

 plant is Amarantus tricolor. M. P. 



DISEASED ASTER PLANTS. 



What causes aster plants to have a 

 black streak from the roots up the en- 

 tire stalk, resulting in their death? 

 yome reach maturity before they die and 

 others die almost immediately. 



J. W. S.— 0. 



The cause of the trouble is a disease 

 which becomes ]irevalent among aster 

 plants during the wet season or when 

 the plants are grown on the same land 

 one year after another. It is useless to 

 try to save the plants after they have 

 become badly affected. The best thing 

 to do is to pull them up and burn them. 



Next season try the following treat- 

 ment for your aster plants: Sow the 

 seed a little later, so that the plants will 

 not become hard and the roots wiry be- 

 fore they are planted outdoors. Do not 

 plant outside before May 15, Give 

 enough room between the plants so their 

 growth will not cover the ground and 

 exclude the sun and air. Use the hand 



LARS PETER JENSEN. 



DENMARK was responsible for the start in life of the new president of the 

 National Association of Gardeners. He was born at Vindinge in 1869 and 

 served his apprenticeship in gardening on an estate near Copenhagen and later at 

 the commercial establishment of H. P. Beyer, Copenhagen, where he became head 

 grower at the age of 20. Two years later he emigrated to the United States. After 

 three years' work with his father in gardening and landscape work at Webster 

 Groves, Mo., he took charge of the .'j-acre Busch place and later of other grounds 

 and estates. His organization activities have been large, including his efforts as 

 flirector of the National Association of Gardeners, director of the American Associa- 

 tion of Park Superintendents, founder and president of the St. I^ouis Association of 

 Gardeners. Mr. Jensen was married in 1897 and has one son, Arthur George, born 

 in 1899. 



cultivator frequently enough to keep a 

 fine dust mulch on the ground at all 

 times during the dry weather. Water 

 only when absolutely necessary to pre- 

 vent the plants from drying up. It is 

 better to place more faith in the culti- 

 vator than in the hose. Give the plants 

 an occasional spraying with Bordeaux 

 mixture, especially in the early stages 

 of their growth. M. P. 



you give me the botanical as well as tlie 

 common name? Tlie plant is not the 

 common wild cucumber, but I believe it 

 belongs to the same family. 



B. G'. C— Minn. 



The name of the plant you sent is 

 Sicyos angulatus or bur cucumber.

CLIMBER IS BUR CUCUMBER. 



Under separate cover I am sending a 

 sample of an annual climber that grows 

 from ten to thirty feet high, is rapid in 

 habit of growth, will cover a wall, fence 

 or anything in a' short time, seeds itself 

 and is easily carried from year to year. 

 It is not a hardy plant. 



I have searched through Bailey's 

 cyclopedia and other books trying to find 

 the name, but am unable to do so. Will
