The Maple Tree Pest

In response to our requcst several days since. Prof. J. B. Steere has prépared the following witu refereiice to the insects in such large numbers on our maples. It vvill be read with niuch interest both here and elsewhere, as the pest seems to be very general thisyear in dift'eient seetions of this State and others : The insect infecting the maples in the streets belonga to the lamily Coecidae, the bark lire, to whtcll the connnon bark louse or seale louse of tlie apple tree and thecochineil insect belong. It is called by Packard Tje.caiiivm acericola, the maple bark louse. The other species of the jienus live on the oratigc and osage oranje, and they are probaljly introduced from the South or Southwest. The perfect insects are winged and too small to be readily notlced. They will be fonnd on the msple leaves. The white, cottony inasses witli the black patches on theiii which are scen on the small branclies of tlie maple are made up of the bodies of ttie témales, which, after a short time, drop tlieir wingsand become tixed,and a cottony exudation from the same, which serves to cover and protect the eggs and young. After cgg-laying the body of the insect shrivels up and dies. The bark ice are provided with beaks with which they pierce the bark and suck up the sap, and the injury they do is in this way. They spread in the winged state and trom their wide distribiition must have been here for several years but not nunicroiis enou;h to be notlced until now. They are not limited to the maple for their food but attack tlie el mi in the streets and are lound in the woodi iipon the polaon ivy and tbc bitlcrsweet, dogwood, and probably matiy others. It also attacks the trompet creeper. Pyrethrnra, or Paris peen, would kill thein, but this will only be of avail with imnll trees or shrubs of value enough to pay for the labor. The maples of our streets and foresta must vvait for natural remedies and theseare already forthcoming. On the maples at Mr. Mack's pluce on William street, there may be seeu on the truuks of the trees, just beneath the branches, clusters of prickly larves, a fourth of au inch in length. From the backs of these are breaking out the perfect IneectS. These are round, llattencd beetles, pale at first but soon turnini; jlossy black with a bloodred spot. on each sid. These, both in the larval and perfect States, mean death to the bark lice and may be Been running along the branches in their search after them. They belon; to the family Coccindlidae, the lady birds. A.11 of them live upon the larves and perfect Insects wliieh (irey upon Vegetatlon and tliis species, chilocoras bivulnernlus, the twloe wounded chilocoras, is especially litted to lollow the pests of trees, wliile others are more at home upon the ground whcre they feed upon the potatoe bur larves and other similar thiugs. These beetles will probably be found in other parts of the city doiug their good work, and they could be very readily carried and colonized upou favorite trees. Ann Arbor, Aug, 11, '8$ Ed, Cor kiek: - We have perused the artlcle In your of the Oih iist. concernlng the trouble in the Telegraph College of this city Seveial other articles of a similar ñutan have been reuil as tliey appeared. We bare forbonie from saying any thlDg Uil forbearanoe h;is ceased to lip: virtue. 'J'lie irticle states lint Mr. M. C. Peter son has uot failed to furnish students a situation, who have completed their worl wlth him. Tliis claim does not surprise us in the least tbr we have good reasons to believ that he will claim most anything excep the trutli. We have been acquaintei not only with the doings of this college but with each and every student wlio bas taken a course of instruction theieii for the past year, and we can positively certify ,that Mr. P. has not placed on student out of nis College in an office at a salary of forty dollars per montl witbln the past 3'ear. It is utterly impossible for him to do so, as lie does not qnalify them tor one neither has he the faculty to qnalify them Ttlegraph Supts. proiiounce the schoo a fraud. A prominent judge of this state has called it a conlidence game. The scholarships and guarrantees that he makee out for his pupils and for whlch they pay fifty dollars, are worthless, or at least the lawyers of this city say they are not worth a snap of the thumb and tinger. Fraüdl Yea, a crime that is committed upon hundreds of young men who come here from more tlian twenty states and from Canada. This golden promise of i $40.00 situation is the means by whicli pupils are induced to enter the "Spider's parlor." ISIr. P has told more tlian one that he has the control of the operators on the Illinois división of the W. St. L. & P. K. lï. and that there need bo no doubt but vvhat he can place students into positions. Fraud again. There is young man in this city, who spent six nionths in this college and then Unee in an office at Elba, Lapeer Co. Mlch. and has managed said office for one week and who has asked Mr. P. to procure a situation for him or ref mul bis money, but Mr. 1'. will do neither. Mr. P. agrees if you come here and do not iind the school as represented he will niiv Hip fu 11 pviipiisH if your trip Iipvo and home again. This is fulfilled as well as the part In regard to situations. He geta possession of a new corner the tirst thing and will not permit him to see any of the students except three or four who are his stool-pigeons, until he has purchased a scholarship. The article states that the fcelings of the students have been aroused by the expulsión of eight, whose work and conduct made such action necessary. The feelings on the part of the students were aroused long before the expulsión took place, and were caused by the General Manager's notfulfllling hiscontraets Wlth his students. The condvet and work is not explahied. Our conduct and work both in and out of school is very good, as any one who knows us can testify. When the expelled students asked Mr. P. why they were treated so, he replied "You know.'1 Yes, we do know. Twenty seven students sent a petition to the Post Master General asking him to investígate the school and if he believed the school a fraud to prohibit the eirculation of the College Heporter and special cali through the mails. The P. M. G. referred the petition to the Asst. Atty. General who n turn referred us to tlie U. B. Dist. Atty. of tliis district. They tlien, July 5tl), sent two of tlieir members to Detroit to consult with s lid Atty. He agreed to lay the matter beíore a U. S. Post Oíliee inspector wlio woukl investígate tlie afiair. The above is what we believe to be the cause of our expulsión. If that i.s rebelliousness, we will accept tlie name as proudly as any true American will when an Eiijflishmnn calis George Washington a rebel. Is Mr. P. afraid to have hls school investigated? Yea, lie is not willing tohave his dealings with the youths of this land exposed to the public gaze. Sueh an exhibition will show its corruptness. We beg leave to sav right here that Mr. P could not have expelled us for drunkenness as wc never drink any intoxicating liquor. Several months ago the students appointed a committee of five to draft an article exposing the school, obtain testimoniáis from departed students, and have them published and circulated, as widcly as possible. When all was ready for the press Mr. Poterson bribed the chairman who in turn destroyed all the work. We were a member of that coinmlttee and know. Other students were also bribed to keep quiet. Mr. P has averred to us that he iears no student. He declares that after a young man has come here and founcl himself defrauded that he (young man) is too much ashamed to ever write home and acquaint his friends of the fact. Let Mr. P. come forward and give the true reasons of his leaving Oberlin, O. He claims that he has sent a large number of students into offlees diirlng the past year; let hun couie forward and give their names and present addresses. Much mondarle work might be written. We respectfully invite yon, Mr. Editor, and the public to investígate the school and satisfy yourselves. Satisfy yourself of our standing morally, etc. The above letter is written in hopes that the school inay beooine known as it is. We would gladly beiald tlie truth over all the land for the benefit of all the young men and women. No student who goes fmiii tliis school will recomniend any of ble friends to come here to learn telegraphy, etc. Hojiing that this will tind the way into the columns of y our paper, we ïeniaiu. Yours 'i'ruly, Box 5515. Aun Arbor, Micli.
