94 STATE BOAKD OF AGRICULTURE. 



ELM, llOCK—Ulmus racemosa. 



This valuable tree tlirives on rich loamy land. It can be easily distinguished 

 from the other elms by its corky limbs. It grows rather slow. The timber is 

 valuable for some parts of farm implements, freight cars, etc., etc. It is tough, 

 but a little inclined to warp and not to keep its shape. The wood is softer than 

 white oak or hickory, except in a few cases. A specimen stands on the flats 

 near the brook north of the rustic road bridge on the College grounds ; also some 

 may be seen in the grove of trees near the road opposite the house on the Par- 

 melee place. 



ELM, WHITE. 



See rock elm ; also American elm. 



ELM, SLIPPERY. 



See red elm. 



See American elm. 



ELM, WEEPING. 



FILBERT— Carj/ius Avellana. 



In the autumn of 1873 Professor Beal obtained seeds of filberts grown at 

 Union Springs, Cayuga county. New York. From these sprung some thrifty 

 plants now at the College. One stands in the hollow just south of the foot- 

 path, between the houses of the Secretary and Professor Cook ; also in the 

 arboretum. 



FIR, BALM OF GILEAD.

FIR, SILVER.

FIR, SCOTCH. 



See Scotch pine. 



FRINGE TREK— C?uona7il?MS Virginica. 



The shrub thrives in Pennsylvania and southward. Another shrub (Rhus 

 Cotinus) is often called fringe tree by some people, but it is more properly 

 called smoke tree. Early in June this true fringe tree produces loose panicles 

 of flowers, each of ^vhich has four slender twisted petals an inch long. A spec- 

 imen stands near the drive west of tlie soutli end of College hall, near the 

 ginkgo tree. This came from Cambridge, Mass. 



GINKGO TREE— iSiziis6uj-ia adianlifolia. 



This peculiar tree is unlike any other tree with which I am acquainted. The 

 leaves are deciduous, fan-shaped, with fork-veins, some like the leaflets of a 

 maiden-hair fern, whence it takes its name. It should be planted not far from 

 a path or building to show its peculiarities, which are very interesting. It be- 

 comes quite a tree, reaching 80 feet or more upward, -with a large trunk, said 

 to be six to twelve feet in diameter. It comes from Japan. Not a twig has 

 been injured by our extreme winters, on our single thrifty specimen which 

 grows in light, poor sandy soil. I know of a few others in various parts of the
