BUFFALO GRASS. A Western 

 indigenous grass of small size, form- 

 ing a delicate mat. and growing on 

 dry, gravelly soils. The s^ama grass 

 is sometimes called by this name. 



BUG. A common word, meaning 

 any insect, but properly applied only 

 to the bedbug (Cimex Icctularius), 

 which is the upe of an extensive 

 family of filthy insects which accumu- 

 late from neglect of cleanliness and 

 laziness. Solutions of corrosive sub- 

 limate in water, ointments with the 

 same poison, and fumigations with 

 tobacco are used with success in de- 

 stroying these insects. Boiling wa- 

 ter poured into the crevices of beds, 

 and repeated every week during 

 spring, is verv efficacious. 



BUHR-STONE. The mill-stone for 

 flouring ; it possesses great hardness 

 with little brittleness, is cellular, of a 

 bluish gray, and feebly translucent. 

 The best kind has a texture nearly 

 half cellular, and is entirely silicious ; 

 the pieces or panes of rock are bound 

 together by hoops of iron when set 

 up for use. The great and valuable 

 supply of buhr-stone is from near Par- 

 is in the lacustrine deposite, above the 

 gypsum. It is the latest rock forma- 

 tion known. 



Buhr-stone has been discovered in 

 Georgia, near the South Carolina 

 boundary, about forty miles from the 

 sea. It lies above shell limestone. 



BULB (from 3o?.6or). A rounded 

 body, having the properties of a bud, 

 usually growing in the ground, but 

 sometimes produced by the flower 

 stalk. Bulbs are tunicated, as the 

 onion, and squamous or scaly, like the 

 lily. Many bulbs, when cut down 

 through the centre, and planted in 

 pieces, produce several plants. On- 

 ions are cultivated in this way in 

 Russia. The adjectives bulbous, bul- 

 bosus, are formed from bulb. The 

 fleshy, solid root-stock of orchis is 

 not a bulb, hut cormus. 



BULBODIU.M. An underground 

 stem resembling the root-stock. 



BULL. The excellence of the bull 

 should be well considered in breeding. 



BULLACE. A wild plum of a light 

 colour. 



BURDOCK. Arctium lappa, and 

 bordana. Troublesome, long-rooted 

 weeds, difficult to eradicate. Their 

 medicinal qualities are imaginary. 

 BURNED CLAY. See CUni. 

 BURNED EAR. The disease pro- 

 duced in grain by the Uredo carbo. It 

 resembles smut, but does not attack 

 the interior of the seed. It is most 

 common on heavily-dunged lands in 

 moist situations. Brimng, especial- 

 ly in a brine containing a little blue 

 vitriol, is efficacious in destroying its 

 eflects on grain. 



BURNET SALAD. Poterium san- 

 guisorba. It grows on the poorest 

 calcareous soils, and is perennial. It 

 may be propagated by cuttings or 

 seeds. The leaves taste and smell 

 like cucumbers ; hence its use in 

 salads. It is relished by sheep. 



BURNS. A lotion of clear lime- 

 water and linseed oil applied with a 

 rag, and cautiously guarding from ex- 

 posure to air, dust, or to injury, by a 

 bandage, is the best treatment. 



BURSA MUCOSA. Small bags 

 containing a fatty mucus, situated be 

 tween the joints in all animals. 



BUSH. Any shrub which natural- 

 ly throws out branches near or under 

 ground. Wild bushes are destroyed 

 by grubbing, by cutting down during 

 summer, or by tearing up with oxen. 

 July is the best month for cutting 

 them down. 



BUSH DRAINING. Placing bush- 

 es in the water-way of drains : the 

 tops should be against the current. 

 It answers well enough for twelve or 

 more years, but is not so permanent 

 as other means. 



BUSH HARROWING. Drawing 

 a bush attached to a chain over bro- 

 ken lands or seeded fields ; or, when 

 a weight is used, and thorny branch- 

 es, it is sometimes employed to scar- 

 ify meadows and prune the grass 

 roots. An old gate may be used as 

 a frame, or the more substantial con- 

 trivance figured on the next page. 



BUSHEL. A measure containing 

 4 pecks, 8 gallons, or 32 quarts. It 

 should contain 80 pounds of water, 

 or 2218192 cubic inches of capacity, 

 to constitute an imperial bushel. The
