Show FIELD, FARM, "AND GARDEN PLANT LIt'H. j One of the most tlestnietivciigeiu'ics union our shruhs unit yotuis fruit trees, is the liec wliieli arc found adhering ad-hering to their hark. The genus to M'hieh plant lieo belong is culled aphis, from a Greek word wliieli signilies to exhaust, ex-haust, tleseriliing the manner, imvliieh iU mischief is accomplished. V propose jit this time to write only of the two most common forms of the phtnt lice, ono being green ;uul the other black. The bodies of the insects of this genus arc short, oval and soli. The plant lice are furnished ut the hiudcrextreniities with twolittle tubes or knobs from which exude almost constantly, minute drops of fluid as sweet as honey. Their heads are small, their beaks arc very long nnd tubular, their eyes globular, and their Jintemue long. Their length is about the eighteenth of an inch. The young are produced alive, there being six or seven broods in the course of a season. sea-son. The young soon attain to maturity, and , become producers, so that the progeny of ouo individual will often amount to many millions in a single season. All these broods are composed compos-ed of femaies, excepting one or two, nt the least, which are mixed male and female, both sexos tiii- time being winged. These leiiniles lay eggs, depositing de-positing them in crevices or depressions depres-sions of the tender bark of young trees and the sprouts of older trees, which are hatched hi due time in tho spring; and the young lice at once begin be-gin to absorb the sap, and increase rapidly in si'c. These (-renin res will often be found herding together in dense masses, each one remaining fixed to the plant without changing their places till they have exhausted the part attacked. j At times, particularly, when disturbed, dis-turbed, they kick and sprawl, throwing throw-ing up their legs in a most ludicrous manner, but too eager for their food to withdraw their beaks from the tree. Little by little globules of sap will often be seen adhering to their Ixtdies, and sometimes a jerking of the Ixxlics of the whole group, as .though magnetically affected, will 1 send' a shower of the tiny drops over the bark and leaves below, causing an appearance which is called honey dew, and which is generally a sure indication of their presence. Another Ano-ther evidence is presence of ants busi-shrub busi-shrub or tree. Arriving at 'Jie'vtcinirC of the lice they greedily devour the j sweet fluid upon the surface, when this is exhausted resorting to the lice themselves. The lice do not seem in I tho least annoyed by thym; on the I contrary the two classes live on the most amicable terms; the ants drain-1 ing food from the lice and protecting them from enemies. There arc many ways of accomplishing accom-plishing their destruction. A good method is to dip the shoots attacked by them into a solution of tobacco one thorough dip being sufficient. This should be prepared by steeping the tobacco for several days, until the water assumes a deep brown color, yet care should bo taken to test the solution on some useless foliage, lest it spoil the shoot, and a valuable tree be destroy at. If the branch or tree cannot be managed in this way, the solution may be applied with sufficient completeness com-pleteness Ijy means of a syringe. This process should be repeated ns ollon ns any of the aphides make their appearance. The proper time of treatment is after sunset. TliT-tree TliT-tree should nt once be trented with the proper fertilizers, to render it more vigorous and able to overcome il-s exhaustion from the attack of the insects. Very strong lye is also an excellent wjwOi fur the bark: but, as with tobac co, care must be taken against its injuring in-juring the loliagc. J-Jxcfuunjc. COTTONWOOD TREKS. All Iowa correspondent writes: I road, in reference to the cotton tree, that "there is a period of eight or ten days during which the air is idled with the cottony down of seeds, causing caus-ing much annoyance," which is literally true and even more, a positive posi-tive nuisance to every housekeeper j who lias this tree for shade. It fills the nose, and perchance tho mouth, while asleep, and the eyes in addition while awake, the milk-pan, the cream-cup, and every closet or room .where an open window or dmc will permit its ingress, and yet it jfc quite a popular tree with us prairie timers, land is becoming more so from the fact ol its hardiness and rapid growth, as every one who chooses can have the comfort of a shady grove of from ten to twenty feet in hight injirc vears. But my object in writing is to inform all who will profit by the information in-formation that there is no need of the annoyance referred to. Tho cottonwood is dioecious, and hence all this annoyance of Hying cotton can be prevented by taking cuttings from male trees only. The cuttings grow rapidly when set out in rows or in plantations for groves, and in five yen's time will make hirjcr and finer trees than youifj trees of four feet high transplanted at the same time, as has been proven by thousands thou-sands of prairie fanners who have tried it. The selection of cuttings from male treescanbcnia.de about the 1st of June, when the cotton is flying from the female trees, but the male trees will be observed to have none. I would like to inquire if there is any distinguishing mark between the male and female coctonwood trees except while in blo:?som. The male trees are in blossom and shed their pollen some two or throe weeks before the male trees shed the seed. A little observation will distinguish dis-tinguish the male flowers, but the proper way would seem to be to observe ob-serve and mark a male tree and lake cuttings therefrom at the most suitable suita-ble time. Jurieulluml Ji-p-rf. I oiiai'k Lri;rn;i:. AVe would mention a f;n-t which has come within uur observation and experience, which, if generally lni is of sonic importance. It is this: That the fruit bud from the base o! the last year's cane throws out larger nnd belter developed grapes than either the first or second. The grapes from these buds seem alo "heltei llavored, and generally superior te those on the first and second. Ia ac- leonlnut'O with this hint, we have adopted the plan nf cutting the cane at such lcuglh ns to leave the third bud generally, nnd sometimes the fourth, when n good strong one, and then rubbing oil' the lht and second buds, nnd leaving the third and fourth for fruit. If the vines are strong nnd vigorous at three vein's, from two to three bunches of grapes may be allowed al-lowed to manure on each without injury. in-jury. fl'lirill I'tlfilir. 1'iYKtt. |
