FLUX, or S.p-rr,ov, Fluxus ianbilicalis, a disease frequently occurring in plants and trees, when the alburnum, or sap-wood, is wounded during the spring ; an 1 sistsof a saccharine, mu- cilaginous fluid, resembling ho- ney-dew. This affection occasions great trouble, especially when vim 3 in hot-houses are prnn< I too late in the season ; for the whole branch is liable to bleed to death, in con- ■nce of the loss of the sap, which ought to supply the young- buds with nutriment, and expand their foliage. There are some perennial plants, such as the cow -parsley, or B . im sphondylium, L. the roots of which, if the stems be severely wounded, or entirely cut off, when they bave attained a certain height, are liable to decay in consequence of this flux, or loss of the umbili- cal fluid. — Hence Dr. Darwin observes, it has been recommended to mow down, early in the spring, thistles, and such other noxious weeds as are troublesome, on ac- count of their rapid increase 3 be- cause many of them will perish, and the rest will be considerably weakened by the great discharge of sap that flows from their wounds at that seas;.M. With respect, to trees, there is another period of sap-flow, that occurs when the new buds are ing, after Midsummer, It is very injurious to wound ! • at that period ; and, as their I 'tion •-, thus 1 ridangered, dif- ferent application! have been re- FLY commended by gardeners. Dr. Darwin is of opinion, that a bit of sponge, if bound upon the end of the cut branch, or upon the wound, by means of some elastic bandage, will be the most certain remedy to save them ■> or, a wire may be substituted for t:e sponge, if twisted so tightly round the end of the maimed branch, as to check the circulation of the juices, and consequently to destroy the part above the ligature. FLY, or Mused, L. an order of insects divided into several genera, ich we shall notice only those species that are more immediately conne6ted with agriculture and do- mestic economy. 1. The Dolphin, or Bean-fly. See vol. i. p. 205. 2. The Corn, or Hessian-fly, a native of the Landgravate 11 ;s , a- ':> .cc it has received its name. This insect is particularly destruc- tive to wheat-corn, in which it de- posits its eggs close to the ground, while growing. — When tae young vermin are hatched, they continue tor some time in a worm-state, feeding on the tender part of the stalk, the growth of which is thus effectually checked. The 1 lessian- fly committed great depredations in the Eastern counties of England, several years sine:-; and, in the year 1/87, did incalculable damage in the provinces of Pennsylvania and Maryland, in America. The only efficacious remedy hitherto discovered, consists in facilitating the vigorous growth of the plants, 1> properly manuring and cultivat- ing the soil ; which practice, as it Will admit of late sowing, will greatly retard their progn ss, 3.
