bruised and damaged by shipping. It is thonglit tliat bcltt-r results would have 

 been obtained with the Japanese varieties if Ihc scions could liave l)een cut from 

 trees in the vicinity. 



"A larger percentage of the scions of the Japanese varieties died after gnnvth had 

 commenced than of the European species. .V few Ridgely scions were broken off by 

 winds, but besitles these only one stock lost Ridgely scions after their growth had 

 l)egun, while 22 lost IMcFarland and 4'A lost (-oe scions wiiich iiad already started to 

 grow. 



" The results of the work of liiOO conliriu the conclusions reached in iSiiS, that the 

 best time for chestnut grafting in Connecticut is about the middle of May, when the 

 stocks are well advanced in foliage." 



Of the scions set between May 11 and 25, 42 jier cent lived, or stated differently, 

 (50 i)er cent of the stocks carried living scions. 



Pecans in Texas {Fru'dman^ s Guide, 10 {1900), No. 5^(J, pp. IJ, 13). — A tlescrip-

B-aising Ficus elastica from the seed, P. Van RoMBUiMur ( Teysinamiia, 'J {1900), 

 Xu. 7, pp. .j'51-ooo'). — Many of the seedlings used in the conunercial plantings in 

 Sumatra are obtained by keeping the ground under the trees free from weeds and 

 collecting the seedlings that come up naturally. 8eeds of Ficas elastica have also 

 been known to germinate freely in the clefts of trees and on old roofs. In all cases 

 the seedlings produced the tul>erous thickening said to be characteristic of F. elastica. 

 Seedlings for commercial purposes may 1)e grown by sowing the very small seeds 

 thickly on the surface of tine moist garden loam, in earthenware pots, which should 

 be kept under cover. In favoral)le circumstances the seed will germinate in about 

 2 weeks, Init often a much longer time is re(iuired. The young seedlings have ten- 

 der, light-green leaves, and the nervation differs from that of the mature leaf. Great 

 care is necessary to prevent damping-off. Before being planted in the jJace where 

 they are to be permanently grown, the seedlings should be transplanted to the nurs- 

 ery and kept there for about a year. — h. m. pieters. 



Rubber in Guatemala, J. C. McNally ( U. S. Consular Rpts., 65 {1901), No. 246, 

 pp. o71-37o). — The culture of Castilloa elastica in Guatemala is popularly described, 

 and estimates given regarding the industry. Good rubber land costs about $100 an 

 acre. About 100,000 trees can be grown on 115 acres. The trees will l)ring in a 

 return of $1 to $2 apiece, beginning with the seventh year (jf the i)lantation, and 

 continue to produce idetinitely.
