The use of a growing fertilizer on pineapples? al the beginning of winter has been 

 found objectionable, since when the plants are started into growth at this time, they 

 are more easily injured by cold weather \\ hich maj follow in January or February . 

 Ground tobacco stems may In- used in the fan, since this material <!<>«•> n< <t cause 

 much growth, but tends to tin- production, rather, of hardy plants, better able to 

 withstand the cold. 



"Within ."» weeks, or as soon :i- p< >ssible aftef >. -t t i i ilt out, the plants should have a 

 light application of cotton-seed meal iii the I'ud, about a tablespoonful to the plant. 

 The first regular application should be put on broadcast about 6 weeks later, and be 

 thoroughly worked in with the scuffle hoc" The experiment brought out clearly 

 that when the quantity of fertilizer was increased from a little more than a ton to 

 nearly 2 tons per acre, the number of larger sizes of pineapples was increased to a 

 \ct-\ profitable extent. 



The pineapple crop was injured in L905 by a frost in February, and some observa- 

 tions were made to determine the relation between the different fertilizers and the 

 Erost-resistance of the crop, bul no satisfactory conclusions could be drawn.

Relative to the picking of pineapples the author ,-tates that before reaching full 

 maturity the pineapple is dark, black-green in color and the eyes somewhat pointed 

 and angular. As maturity advances the eyes flatten down somewhat in the center 

 and become slightly elevated around the margins, and the color changes to a very 

 pale green. " The opening and spreading of the crown may he taken as one of the 



best indications of maturity \s the fruit ripens the stem elongates, the 



Blips grow rapidly and fheir leaves spread out." In summer fruit intended Eor 

 short-distance shipments and immediate consumption the basal eyes may be allowed 

 t<> retain some color. " If considerable time is to elapse between picking and con- 

 sumption, the fruit should not be quite s ature." 



The mango in Hawaii, J. E. Higgins I Hawaii Sta. Bul. 1 .', pp. ■:.', />/*. W). — 

 A popular treatise on the culture of mangoes in Hawaii. In some experiments made 

 to determine the longevity of mango seeds it was found thai of seed .'il to 11 days 

 old, 4:;.") per cent germinated and produced good plants. These figures indicate that 

 the seed can be preserved much longer than is generally supposed. An analysis is 

 given of the mango, which shows it to contain 82.51 per cent water, 0.39 per cenl 

 ash, 0.01 per cent fat, 1.45 percent fiber, 0.84 percent protein, and 14.80 per cent 

 carbohydrates. 



Directions are given forthe manufacture of chutney, marmalade, and jelly from 

 mangoes, and notes are given on mango breeding, diseases and Insects affecting man- 

 goes, varieties of mangoes, and mango seedlings in Hawaii.
