Report of the coffee testing gardens at Bangelan, T. WrRTii (Jaarh. Dcpt. 

 JjtDiilli.. MJr. Ill llinidcl \ rdcilaiiil. Jiitlii'\ I'.iJ.i. jti). //.J— >7, pis. 3). — A jiroKress 

 reix>rt on culturiil .iiid selection studies with various kinds of coffee. 



Diila secuHMl willi reference to the sterilitj' or self-fertility of coffee lilooms 

 indicate tliat a certain amount of fruit was set when the blossoms were pro- 

 tected fronj outsi(U' judlination. Tests are to be conductt^l further to determine 

 whether the seed from close pollinated fruit is viable. Data are given on the 

 yields secured in 1011. 1912. and 1013 from seedling ]»lants selectefl from various 

 mother trees. A test whidi has been conducted for three seasons to determine 

 whether Kobusta and Quillou coffees can be grown better as single-stem plants 

 or as nuiltiple-stem plants has thus far shown very little difference in yield. 

 In some topping exjieriments with these two varieties the trees were headed 

 back at different heights ranging from (» to 12 ft., and the results indicate that 

 the higher the trees ai'e toppwl the greater the yield of coffw. For the three 

 years of tests untopi)ed trees gave somewhat better yields than toppe<l trees. In 

 a test of tlie viability of coffee seed jrtaced in storage, samples of Robusta coffee 

 seed which had been stored in dampened powdered charcoal for a period of five 

 months give a total germination of G7 per cent. 



[The influence of fruit flies on the qviality of coffee], E. Y. Wii.cox (Hfuraii 

 8to. Upi. 191 'i, p. 22). — Analyses were made of samples of coffee from coffee 

 cherries uninfested with fruit tly, badly infested with fruit fly. and also from 

 half-ripe cherries taken four or five days before they would be completely ripe. 

 No chemical differences in the composition were noted in the different samples. 

 Coffee was prepared for drinking from all the samples by three different meth- 

 ods and was submitted to several persons for their opinion as to the flavor and 

 other qualities of the different samples. The various rei>orts agreed that the 

 sample from the infested fruit was slightly insipid and ix)or in quality, while 

 that from the fruit not quite ripe was best in quality. The deterioration in 

 quality in ripe coffee berries is attributed to the fermentiitiou of the whole 

 cherry which rapidly develops a putrefactive odor. 



A further test was made to determine whether infestation with the fruit fly 

 might cause a loss of weiglit in coffee. It was found that the weight of 1 terries 

 from infested coffee cherries immediately after pulping was 5 per cent less than 

 that of berries from uniufestetl fruit. When tlie coff'ee came to a constant 

 weight and was considered dry, however, the weights of the two lots were the 

 same. Hence it appears that little or uo loss in the weight of the coffee berry 

 is caused by infestation by the fruit fly.

 garden conditions. A sunnuary is given of the more important vegetative char- 

 acters of the different species. Only those species are considered at length which 

 have been observed growing in more than one locality.
