History, Use, Propagation, Culture, 
1567. Mullera. In honor of Otho Frederick Miiller, a Dane, one of the editors of the Flora Danica. There 
have also lived four other MuUers, Germans, and botanists. The fruit is remarkable for its form, which is 
that of a necklace ; a number of little balls being united by stalks, and not opening as in other leguminosee, but 
always remaining closed. The flowers are pink, and the size of a bunch of Laburnum, 
1568. Robinia. In memory of Jean Robin, herbarist to Henry IV. of France, author of Histoire des Plantes, 
&c., Paris, 1620. His son, Vespasian, was subdemonstrator at the Jardin de Roi, and was the first person 
who cultivated the R. pseudacacia in Europe. 
R. pseudacacia is a thorny fast-growing tree, of middling stature, of no great beauty as a tree, but orna- 
mental when young, and very well adapted for copse-wood and rough timber. The leaves come out late in 
spring, and fall off early in autumn, like those of the ash. The timber is much valued in North America, and 
said to be superior to that of the laburnum ; "being close-grained, hard, and finely veined; and in America 
more valued by the cabinet-maker than any other native timber whatever. Pursh, in his Flora, asserts, that 
being nearly incorruptible, it is equally useful for posts and gates. We are informed by a friend, that gate- 
posts of this timber, on a property near Baltimore, have remained fresh for nearly a century. The finest pin- 
nated leaves, and pendulous white odorous flowers, add greatly to its beauty. Its value is scarcely known in 
this country." {Caled. Mem. ii. 414.) It prefers a deep sandy soil, and rather sheltered situation ; being very 
apt to throw up suckers from the running roots, and as it stoles freely, it seems peculiarly calculated for cop- 
pice-woods. Beatson {Com. to Board of Agr.) has cultivated it in this way to great advantage. 
In North America the use of the locust-tree has hitherto been confined to trenails, on account of its scarcity, 
but were it as plentiful as oak, it would be applied for more purposes by the shipwright, such as knees, floor- 
timbers, and foot-hooks, being much superior to oak for its strength and duration, and, from the tree spreading 
into branches, affords full as large a proportion of crooks or compass timber as oak. 
A cubic foot of acacia, in a dry state, weighs from 48 to 53 pounds avoirdupois. If we compare its tough- 
ness in an unseasoned condition with that of oak, it will not be more than 8 — 100 less. Its stiffness is equal 
to 99 — 100 of oak ; and its strength nearly 96 — 100 ; but were it properly seasoned, it might, possibly, be found 
much superior to oak in strength, toughness, and stiffness. A piece of unseasoned acacia, two feet six inches 
long, and an inch square in, the vertical section, broke when loaded with a weight of 247 pounds avoirdupois. 
Its medium cohesive force is about 11,500 pounds, {Diet, of Archi.)
