Ban Eun Kon and that when brought to Bangkok from Nakon 

 Chaisri, only an hour or so distant by rail, it reverts to the Ban 

 Eun Non. The Nakon Clmisri pummelo can not be shipped for 

 various reasons ; the main one is that it loses its aroma. 



"The citrus fruits differ considerably here; for example, all 

 citrus fruits grown south of Bangkok and also nearer the sea are 

 fgr superior to those north of Bangkok. A matter of 8 miles or so 

 makes a great difference. Those grown south of Bangkok are irri- 

 gated or inundated by very salty water, as the tide carries the salty 

 ocean water up the Menam River and into the Klongs. When 

 planting the Nakon Cliaisri pummelo elsewhere the natives always 

 add salt to the soil. 



" North of Bangkok the river water is quite sweet. I tasted 

 mandarins, choice fruits gro^^^l south of Bangkok, and fruits from 

 stock which was derived from the southern garden but grown 

 north of Bangkok, and the difference was tremendous. Those 

 grown south of Bangkok sell for 6 ticals per hundred, and those 

 grown north of Bangkok, although larger, sell for 3 ticals per 

 hundred because the aroma is not comparable." 

 52389. "(From Bangkok, Siam.) Thong Dee pummelo. Seed pre- 

 sented by Doctor Yai, Minister of Agriculture. Doctor Yai con- 

 siders this the best pummelo of Siam ; it is a little acid and so is 

 better liked than the Nakon Chaisri, which is very sweet; it is a 

 splendid shipper and has quite the' aroma of the Nakon Chaisri. 

 The Thong Dee pummelo does not lose its flavor when planted 

 elsewhere ; it produces seeds and is also seedless at times." 



52390. Pteeocakpus macrocaepus Kurz. Fabacese. 



" From Korat, Siam. The mai padou, one of the finest timber trees of 

 Morat. It grows to a height of 150 feet with a girth of 10 feet at 4 feet 

 above the ground. All the wood, or nearly all, is bought by Japan ; it is 

 verj hard and splendidly adapted for furniture and also for construction 

 work." 



52391. QuERcus TKUNCATA King. Fagacese. Oak. 

 •'(No. 75. From Bangkok, Siam.) A valuable oak which grows on dry, 



shady, or gravelly slopes, at an altitude of 2,400 to 5,000 feet, and I 

 should think that it would thrive in California and also in Florida. The 

 acorns are very sweet and are eaten roasted. I have eaten many of 

 them myself and they are rather good. The tree is a prolific bearer and 

 seeds are plentiful just now." 



52392. Malus syl\'estris Mill. Malacese. Apple. 



(Pynis malus L.) 



From Kona, Hawaii. Scions presented by J. E. Gamalielson, weather 

 observer, through Prof. W. H. Sherzer, Michigan State Normal College, 

 Ypsilanli, Mich. Received March 29, 1921. 



"A sport found by Mr. Gamalielson, about 15 years ago, growing on a fallen 

 ttee-fern log. He recognized the growing sprouts as being those of the apple, 

 and he brought one to his home. It grew there for some time and bore fruit. 

 From the original tree he transferred a sprout to his present home, and it has
