In England, ever since the death of Lord Bea conslichl (1881), the primrose lias been adopted as the badge of the Conservative Party, in the belief that it was the favorite (lower of their "real leader. This belief is said to be a mistaken one. and to have originated in an incident thai happened at the time of his funeral. The Queen sent a mass of primroses on thai occasion with the inscription, "His favorite flower." meaning her own husband, Prince Albert. It was, how- ever, understood as referring to Lord Beacons- field, so that on the anniversary of his death (April 19th) every Conservative now wears a bunch of primroses, and the day is known as Primrose Day. See Pbimrose League. The United States cannot be said to ha generally accepted national flower. In ISX'.l an attempt was made to secure a general expression of opinion in favor of some one flower, and the goidenrod, as being indigenous and more widely distributed than in any other country, n ived the majority of the suffrages; but a national Bower is usually recognized only when tradition and legend give it. significance, and not because of a popular vote. By acts of the Legislature some States have adopted State flowers: Iowa, the wild rose; Maine, pine cone and tassel; Mich, apple-blossom; Montana, bitter-root; Nebraska, goidenrod: Oregon. Oregon grape; Vermont, red clover; Colorado, white ami blue columbine; Ok lahoma, mistletoe: Utah, sego lily. In other States flowers have been selected l. vote of the school-children, or for other reasons are popu- larly recognized: California, the California poppy; Idaho, syringa; Kansas, sunflower; Min- nesota, moccasin-flower; Nevada, sage-brush; Washington, rhododendron: Georgia.

The dependence of insect life on that of plants is illustrated by the fact that in Germany between 500 and 600 species of insects obtain their livelihood by feeding upon the oak. while in the United States nearly the same number of species have already been found to prey on the native oaks. The elm, wil- lows, and pines also afford food and shelter to hundreds of species, the insect pests of (he apple and other fruit trees also amounting to many hundred species each. Some insects bore in the roots; multitudes of borers penetrate into the trunk, branches, and twigs, as well as hark; while still greater numbers of caterpillars feed FLOWERS ANU INSECTS. uH of the life within the woo.i or in reining the re pro foundly modified i fail liar mode .,1 file, have tened, bodies, are i • wholly, i ir jaw -. bj which thej eat theii 1 1 1 ,!i tl u | and other I lor theii seen in thousand example-, in the opinion of Lan effects upon a Main-, treSSl nation of the form oi the body.
