 The primary division of the leaf in .dl. filicifolia is long 

 and narrow, thrice as long as in D. spectabilis, and 

 tapering to a long point, while in D. spectabilis the pri- 

 mary division of the leaf is short and has 3 well-marked 

 segments. In A. filicifolia the secondary divisions are 

 deeply and irregularly cut ; in D. spectabilis they are 

 merely serrate. The two plants are also immediately

DELAWAEE, HOETICUITTJBE IN. The state of 

 Delaware ( Fig. 084) is situated close to the largest fruit- 

 consuming cities of the New World. An emphatic com- 

 mercial advantage in the development of a diversified 

 horticulture arises from the modifying climatic influence 

 of the Delaware and Chesapeake bays; from a variety of 

 fertile soils; and from the ripening of its fruits and vege- 

 tables between the products of the North and South, 

 There is probably no area in the United States which, in 

 its natural commercial advantages, in its climatic en- 

 vironment, and in the diversity of its soils, is so pre- 

 eminently fitted for the development of an extensive 

 and diversified horticulture as the peninsula to which 

 Delaware belongs. 



New Castle, the northern county, is hilly and rolling, 

 and varies from a dense clay to a clay loam. Horticul- 

 turally, it is well adapted to plum, pear, apple and bush- 

 fruit culture, and, in restricted areas, to the cherry, 

 peach and trucking industries. But the production of

hay, grain, and dairy products is the leading feature in 

 New Castle's rural activities. Kent, the central county, 

 is gently undulating. The soil varies from a clay loam 

 in the northern part to a sandy loam along the southern 

 border. The most diversified horticulture of the state, 

 including tree fruits, bush fruits, strawberries, grapes, 

 and vegetable products, has been developed here. In

 Delaware horticulture was born in 1832, with the peach 

 industry, when the first extensive orchard was set near 

 Delaware City. In a single year the value of its peach 

 crop was $16,000. Then an era of the most rapid horti- 

 cultural extension was inaugurated. By 1840, half a 

 million baskets of peaches were shipped from the county. 

 But in 1842 the peach-yellows broke out near Delaware 

 City, and by 1867 more than one-half of the crop of three 

 million baskets was grown in southern New Castle 

 county. The orchards of New Castle had largely 

 disappeared in 1870, and in 1890 it contained less 

 than 5,000 acres. Kent county, however, in 1890 had 

 23,000 acres, and Sussex county 20,000 acres. In 1899, 

 extensive orchards were being planted again in New- 

 castle county and northern Kent county.
