sect which destroys the Loru?t 

 Tree,*' we would refer our read- 

 ers to the Massachusetts Agricultu- 

 ral Repository, vol. V. p. 67. The 

 insect is there called Cossus Rohi- 

 nioB ; and drawings are given de- 

 scriptive of its different appear- 

 ances, in ditferent stages of its ex- 

 istence. The writer suggests no 

 remedy against its ravages. 



The Massachusetts Agiicultural 

 Repository, vol. V L page 272, 

 contains a paper detailing a num- 

 ber of experiments by H. A. S. 

 Dearborn, instituted for the pur- 

 pose of preserving locust trees 

 from the depredations of insects. 

 For this purpose Mr. Dearborn 

 stopped up the holes, which they 

 had bored into the trees, with lime 

 mortar, and by white washing, &c. 

 He succeeded, however, but par- 

 tially, and proposed to persevere 

 in the spring of 1822. Should his 

 experiment fail, he proposes to 

 head down all his locust trees in the 

 latter part of April, and burn the 

 wood to destroy the larvae. " The 

 trees," he observes, '' are of rapid 

 growth, and the stools throw up 

 luxuriant suckers, and 1 shall soon 

 have young thrifty trees, which 

 can be more certainly preserved 

 from the attacks of the insect, 

 should they again visit them ; for 

 trees which are so large as to have 

 very rough bark, supply so many 

 fastnesses for the deposition of the 

 eggs, and to cover the depreda- 

 tions of the worm that it is is very 

 difHcult to extirpate them."

MADDER, Rubia Tinctoria, 

 The followiug directions for raising 



this plant, are copied from " Tht 

 K/nporiuni of jirts.^^ 



'' This plant ma be propagated 

 either by ottsetts or seeds. If the 

 latter method is preferred, the seed 

 should be of the true Turkish kind, 

 which is called Lizari in the Le- 

 vant. On a light thin soil the cuU 

 ture cannot be carried on to any 

 great profit. The soil in which 

 the plant delights is a rich sandy 

 loam, being three feet in depth or 

 more. 



" The ground being first made 

 smooth, is divided into beds four 

 feet wide, with alternate alleys half 

 as wide again at the beds. The 

 reason of this extraordinary breadth 

 of the alleys will presently appear. 

 In each alley is to be a shallow 

 channel for ihe convenience of ir- 

 rigating the whole lields, <Sic. That 

 part ot the alley which is not oc- 

 cupied may be sown with legtimes. 

 " The madder seed is sown broad 

 cast, in the proportion of from tweii- 

 ty-tive to thirty pounds per acre, 

 about the end of April. In a fort- 

 night or three wetdis, the young 

 plants begin to appear ; and from 

 this time to the month of Septem- 

 ber, care must be taken to keep 

 the ground well watered, and free 

 from weeds. 



"• If the plants are examined in 

 autumn, they will be found sur- 

 rounded with small yellow otTsetts, 

 at the depth of two inches ; and 

 early in September, ihe earth from 

 ihe alleys is to be dug out, and laid 

 )ver the plants of madder to the 

 Height of two or three inches. With 

 this the tirst year's operation ceases. 



" The second year's work begins 

 in May, with giving the beds a
