Calaniagrostis (lensus n. sp. — Culms in large patches, 

 from strong rootstocks, 3 to 4 ft. high, robust, leafy, 5 to <i 

 nodes; the lower sheaths loose and longer than the internodes, 

 the middle ones shorter than the internodes, the upper includ- 

 ing the base of the panicle; leaves often a foot long, rigid, 

 plane or becoming somewhat involute at the long slender 

 points, somewhat scabrous, as are the sheaths; ligule 1 line 

 long, lacerate: panicle strict, lance-oblong, 4 to 6 inches long, 

 rachis slightly scabrous, branches somewhat verticijate, ap- 

 pressed, 1 inch long and densely flowered: spikelets crowded, 

 2 to 2} 2 lines long; outer glumes linear-lanceolate, nearly 

 equal, acute, slightly scabrous, margins slightly scarious; third 

 (or flowering) glume a little shorter, narrow, apex slightly 

 toothed and mucronate, a few short hairs at the base; awn, 



twisted near the base, a little longer than its glume; palet a

little shorter than the glume, thin; sterile tuft, - nder, one-

 pointed, the upper very. short: panicle spike-like, narrow, 8 to 

 •i inches long, the branches in short, approximate (or at the

Simple mechanism to show "roTmpisni.— Take the work- of an old 

 clock run by a weight rather than a spring and support them horizon-

 the wheels may be made to revolve at a much more rapid rate than in 

 the clock. One of the shafts, that bearing the scape wheel, is longer
