[To TIM EDLTOR OF TIED "SPECTATOR."1 SLE,—If Mr. Thorburn has

access to a library he ought to find many references to the "loco-weed." I have no doubt the Agricultural Department in Washington will be able to tell him of special treatises on the subject. The "Century Dictionary," under "Loco-weed," says, "Any one of several leguminous planta producing the loco-disease in animals." Among these are species of Astragalus.—I am, Sir, 8tc., W. H. Smelt-LET. 9 Upper Hamilton. Terrace, N.W.
