ANB 



AXE 



radishes, turnips, &c., by the maggot 

 of a weevil. 



The maggot found in the turnip an- 

 bury is the larva of Curculio ■plcuro- 

 stigma of Marsham, and Rhynchanus 

 sulcicollis of Gyllenhal. " I live bred 

 this species of weevil," says Mr. Kir- 

 by, " from the knob-like galls on tur- 

 nips, called the anbury, and I have 

 little doubt that the same insects, or 

 a species allied to them, cause the 

 clubbing of the roots of cabbages." 

 Marsham describes the parent as a 

 coleopterous insect of a dusky, black 

 colour, with the breast spotted with 

 white, and the length of the body one 

 line and two thirds. 



The general experience of farmers 

 and gardeners upon the subject testi- 

 fies that the anbury of the turnip and 

 cabbage usually attacks these crops 

 when grown for successive years on 

 the same soil. This is precisely what 

 might be expected ; for the parent in- 

 sect always deposites her eggs in 

 those situations where her progeny 

 will find their appropriate food ; and 

 in the fragments of the roots, &c., of 

 preceding crops, some of these em- 

 bryo ravagers are to be expected. 

 That they never attack the plants 

 upon a fresh site is not asserted : 

 Mr. Marshall's statement is evidence 

 to the contrary. But it is advanced 

 that the obnoxious weevil is most 

 frequently to be observed in soils 

 where the turnip or cabbage has re- 

 cently and repeatedly been cultiva- 

 ted. Another general result of ex- 

 perience is, that the anbury is most 

 frequently observed in dry seasons. 

 This is also what might be anticipa- 

 ted, for insects that inhabit the earth 

 just beneath its surface are always 

 restricted and checked in their move- 

 ments by its abounding iu moisture. 

 Moreover, the plants actually alfected 

 by the anbury are more able to con- 

 tend against the injury inflicted by 

 copious supply. In wet periods, also, 

 the atfected plants show less the 

 extent of the injury they have sus- 

 tained, for their foliage does not 

 flag. 



In considering the best modes of 

 preventing the occurrence of the dis- 



ease and of palliating its attacks, it 

 J is apparent that any addition to the 

 ; soil that renders it disagreeable to 

 the weevil will prevent the visits of 

 this insect. The gardener has this 

 in his power with but little difficulty, 

 for he can keep the vicinity of his cab- 

 bage, cauliflower, and broccoli plants 

 sprinkled with soot, powdered tobac- 

 co, or other orTensive matters. 



AXCHL'SA. See Alkanet. 



ANCHYLOSIS. A stiff, immovea- 

 ble joint. 



ANCTPITOUS. Having two edges. 



ANDES GRASS. Arena elatior. 

 Tall meadow oat ; a perennial grass ; 

 flowers in May, and ripens its seeds in 

 July. It is hardy, early, and makes 

 good hay. It is difficult to root out, 

 and lasts a long time. A clay loam is 

 the best soil. Sow two and a half to 

 three bushels with oats. 



ANDROCEUM. The male parts 

 of the flower. 



ANDROGYNOUS. Hermaphro- 

 dite : a union of both sexes. 



ANDROPORUM. An elevation in 

 the middle of a flower, formed in part 

 by the union of the filaments of the 

 stamens. 



ANELLIDES, ANELLATA. The 

 class of articulated animals formed 

 of ring-like segments, as the earth- 

 worms. 



ANELYTROUS. Without elytra 

 or wing cases. 



ANEMOMETER. (Gr. avefioc, the 

 icind, and fiE-pov, measure.) An in- 

 strument for measuring the force or 

 velocity of the wind ; a wind gauge. 



Dr. Lind's anemometer consists of 

 a glass tube, bent into the form of the 

 letter U, and open at both extremi- 

 ties. One of the extremities, A, is 

 also bent round to the 

 horizontal direction, 

 in order that the 

 wind may blow into 

 it. The tube being 

 partially filled with 

 water and exposed 

 to a current of air, the 

 water in the branch 

 at which the wind en- 

 ters is depressed ; for 

 example, to B, and consequently ri-
