the designation by which they are most commonly known. The term 

 "pomelo," however, is the one which is now given the preference, 

 and has been adopted by the U. S. Department of Agriculture, by 

 the American Pomological Society, and by the State horticultural 

 societies of both California and Florida. 



Varieties. The fruits commonly seen in the markets are 

 budded varieties and sustain the same relation to the seedling po- 

 melos of gardens and dooryards as do seedling oranges to the im- 

 ported varieties, such as the Navel or the Valencia. Some seedlings 

 are of peculiarly fine flavor, but, because of the thickness of the 

 rind or other faults, they fall short of the standard set for a market 

 variety. In the future it is highly probable that seedlings will 

 be produced which will have commercial merit, perhaps exceeding 

 those of any introduced variety. There can be no doubt that the 

 fruit, even of the seedlings, can be greatly improved by the best 

 methods of cultivation. They respond freely to judicious care in 

 fertilization and irrigation. The thickness of the rind and the 

 amount of rag may be materially reduced by the liberal use of 

 potash and the limited application of nitrogenous manures. 



The following varieties are worthy of careful trial: Triumph, 

 Duarte Seedling, Aurantium, Colton Terrace, Duncan, Marsh, Royal 

 and Standard. The Triumph and Marsh or Marsh Seedless are 

 reported as having done well in parts of Oahu, in the Territory of 

 Hawaii. The distances between the trees need to be greater than 

 in the case of oranges, because of the more vigorous growth made 

 by the pomelo ; 25 to 35 feet will be quite close enough on good soils. 

 The fertilization, irrigation, tillage, picking, curing, and packing are 

 essentially the same as described for oranges. 



THE LIME. 



The lime or acid lime (Citrus medica acida) is widely grown 

 within the Tropics, but because of its extreme sensitiveness to low 

 temperatures is not at all successful in many orange-growing dis- 

 tricts. In Hawaii it thrives and produces large crops of fruit. It 

 will prosper on rather rocky soils and those too poor for orange 

 cultivation. The propagation is usually by means of seeds only, 

 but budding has been practiced to a limited extent, and will doubt- 

 less be used more extensively in the future. Seeds can not be de- 

 pended upon to reproduce exactly the same form as that of the 

 fruit from which it was taken, but for many of the purposes for 

 which limes have been used uniformity of shape, color, or size is 

 not an essential. The trees should be planted 15 to 20 feet apart. 



Limes are put to many uses. In the Tropics they are freely 

 used as fresh fruit for the making of limeade and in the seasoning of 

 foods. The market for the fruit in this form is increasing in the 

 United States and the demands of the future for a lime of fine qual- 

 ity and appearance are likely to become so stringent that the better 

 forms will be multiplied by budding. At the present time, how- 

 ever, by far the larger numoer of limes are marketed in the form of 

 so-called secondary products. Considerable numbers of them are 

 preserved in brine and sent to Northern markets. Larger quantities
