GRAPEFRUIT 
The Grapefruit industry of today is a growth of not more than seventy years. The increase in culti- 
vation, production, and use of Grapefruit is without a parallel in American horticulture. It ts Florida’s 
greatest single fruit contribution to the tables of the world, and it is in Florida that its culture has 
reached its greatest development. Its consumption has increased faster than the supply. Extensive 
advertising In various ways, resulting in wide distribution, has been a large factor in popularizing this 
comparatively new and very wholesome fruit. In addition, it should be remembered that, tree for tree, 
a Grapefruit planting will produce twice the number of boxes of fruit that orange trees will at practically 
the same cost of production. For example, under the same conditions, assuming that a six-year-old 
orange tree will produce 2 or 3 boxes, a Grapefruit tree of the same age will yield 4 or 6 boxes. The 
market for Grapefruit ts continually broadening, and canning the fruit has greatly widened its dis- 
tribution. On the whole the Grapefruit outlook is very satisfactory. 
~Duncan Grapefruit 
We consider Duncan the fest early Grapefruit grown. During all the years we have been in the 
citrus business (and during this time we have grown, observed, and tested a host of varieties), we have 
never found a Grapefruit which is quite the equal of Duncan m all-round desirability. It has everything 
a Grapefruit should have, and is lacking in no particular. Its size is exactly what the markets want and 
pay best prices for—54’s to 70’s_ Its shape is round, slightly oblate, and it packs well. Color a clear 
light yellow, with oil-cells showing through the smooth skin The juice content is particularly heavy 
and possesses more than any other Grapefruit the true sweet-bitter-acid-grapefruit flavor. The season 
of this fme Grapefruit is an extended one. It is ripe enough in color and quality to ship in early No- 
vember, and it can be held on the tree without deterioration until late m May. We have been propa- 
gating Duncan for more than a quarter of a century. Our first budwood was secured from the original 
Duncan tree at Green Springs, Fla. It has weathered the storms, cold spells, and neglect of more than 
eighty years and ts still bearing good crops. Through all the cold periods which we have experienced 
during the past quarter of a century, both in north and south Florida, we have observed that Duncan 
invariably has suffered less than any other variety. It is unquestionably the hardiest of all the Grape- 
fruit. 
~Marsh Seedless Grapefruit 
This fme variety originated at Lakeland, Fla., and was first brought to notice and grown by C. M. 
Marsh, about 1895. Its most marked characteristic Is its practically seedless fruit. Its marketing sea- 
son begins in January, and, because it is so nearly seedless, the fruit can be held on the trees later than 
all other varieties. The fruit is very handsome mn appearance, with smooth yellow skin. The quality ts 
fine, a great favorite in the markets, and always commands good prices. It is becoming known as a 
distinct variety, and sells, not simply as Grapefruit, but under its own name. Like all other varieties of 
Grapefruit which we grow and recommend for commercial planting, Marsh Seedless frurts run in the 
sizes most desired by the fruit trade. 
The tree makes a low, dense, spreading head, often measuring more across the spread of the 
branches than it does in height. It bears heavy, regular crops. In every well-balanced planting, Marsh 
Seedless should be given a liberal place. 
~ McCarty Grapefruit 
Many years ago. the McCarty Grapefruit, an Indian River variety named for the late C. T. Mc- 
Carty, attracted our attention. After keeping it under observation for several years, we decided to 
propagate it. It possesses in a marked degree the distinctive habit of producing its fruits singly in. 
stead of in bunches or clusters. This feature, coupled with its late ripening period and its very high 
quality, has so impressed u_ with its merits that we have come to regard McCarty as one of the fmest 
Grapefruits grown in Florida today. Because it does not grow in clusters, the fruit is very uniform in 
size and shape, and very free from those blemishes caused by clustering, such as extensive scale injury 
and misshapen fruits. We believe this variety is not surpassed by any other as a regular, uniform 
bearer. The fruit is of best market size, light, waxy yellow m color, with skin of beautiful texture. 
It is distinctly a fancy fruit; has a perfect Grapefruit flavor and the flesh 1s melting, free from fiber 
and rag when properly grown. It is the favorite for canning.
