Another table is given which shows the composition with reference to sugars and 

 acids of the various parts of the pineapple. From the figures given it is shown that 

 the sugar decreases and the acid increases from the base to the crown of the fruit, 

 and from the core to the circumference. The sweetest fruit, therefore, of the pine- 

 apple is at the base near the core. 



Cacao manurial experiments at Grenada (Agr. News [Barbados], 3 (1904), 

 No. 66, p. 347). — The amount of cacao obtained during each of the years 1900 to 1904 

 on plats fertilized with manure and with different quantities and combinations of 

 commercial fertilizers are tabulated. No conclusions are drawn. 



Facts as to date culture, A. V. Stubenrauch (Pacific Fruit World, 18 (1904), 

 No. 5, p. 7). — This article was written for the purpose of cautioning intending date 

 planters not to be too hasty in setting out large orchards in the vicinity of the Salton 

 basin until further experimental work shall determine just what varieties will best 

 succeed and just what difficulties may be encountered in the work. 



While theoretical considerations as to summer climate may show the Salton basin 

 to be especially well adapted to date culture, meteorological data on the winter 

 climate have not accumulated in sufficient quantity to make certain that the trees 

 will flourish over winter. It is believed, therefore, that intending planters should 

 await the results of the coming winter, rather than to plant blindly and then be 

 disappointed in the future. The purpose of the article is to arrest the booming of 

 date culture, but not in any way to stop the development of the industry along 

 rational lines. 



Making a cranberry bog, F. A. Makepeace ( Country Gent., 69 (1904), No. 2693, 

 p. 819). — Detailed directions are given for making a cranberry bog. After the plants 

 have been set it is about 4 years before they come into full bearing. Once estab- 

 lished, a good bog should bear steadily for 10 to 12 years without doing much to it 

 other than keeping it free from weeds and the ditches cleaned out. The average 

 annual production of an acre of good bog is placed at 100 bbls. With the cranberry 

 picker a skillful operator will average about 10 bbls. of fruit per day. 



Trial shipment of grapes to England (Jour. Dept. Agr. West Australia, 10 (1904), 

 No. 1, pp. 24-27). — Different varieties of grapes were shipped to England in a number 

 of different packages. They arrived in England about 5 weeks after picking. All of 

 the varieties had lost their bloom and fresh appearance, and the stalks had become 

 discolored and somewhat shriveled. 



The varieties which had been packed in cork dust arrived in decidedly the best 

 condition, those packed in paper only did not look so well, and those packed with- 

 out any cork dust or covering at all were in the worst condition. For carrying pur- 

 poses, therefore, the cork dust is recommended as preferable to any of the methods
