AmoDg the mineral or inorganlc Insecllcldes the arsenlcal compoundB lake the tlrst rank frora thelr cheapness and general utlllly The objectlons to tbelr use are First, that they are dangerous to man and domeailc animáis; Second, they alo lnjure plant life when used In too great quantlly, and Thlrd.they affect the sioinach'B only of Insecis, and no are of use only agatnst such lasects as blte off the outer parts of leaves and buds. Insect whlch bore deep into leaves or stems to suck the Julces are not much affecti d by these polsoiif. Tliree forms of arsenlc nre nsed Paris greeu, ludou purple and whlle arsenlc. The iniai commonly used Is Paris green. Paris green cost40cent8 per pound In Ann Arbor at the present time. The proportlons used are one tablenpoonful to t ur gal lons ol water, or one pouud of Paris green to twenty pouuds of flour. The lnsecls for whlch lt Is usually applled are potato beetles, curraut worms, caDbage worrns, canker worms and codllng mot h. London purple Is clalmed by C. V. Rlley and other experts to be In general as effectlve as Paris green. The proportions used are oiie-hnlf pound to 1 poundo of flour or other dry BUbstance. lt Is used for the same lnsects as Paris green. LmiiUni purple costs in Ann Arhor 'M ceuts per pound. The thlrd torm of arsenlc Is white arsenlc. Thls Is worth cxperlmenllng wlth. C. V. Rlley glves thls formula. Boíl one pound white arseulc and one pound sal soda In a gallon of water untll the arsentc Is dlssolved, tben use one quart of thls to lorty gallona ot' water, use for the same Insect and In the same way as Paris green. White arsenlc can be bought Ín Ann Arbor by the quantlty at 8 cents per pound, and sal soda al flve cents. White arsenic is more dnngerous tlian either of the other forins of arsenlc, becuuse lt Is white In color and muy easlly be taken for S'unethlng barmless. tihould becolured by soluble Prusslan blue. Paris green from 1U high prlce Is more apt to be adulterated I han the otliers, whlch are Ho chaap that tbey are hardly worta the tnmble of adulteratton. The fear that such a common use of forms of arsenlc would polson the ground tiually seems to be considered without foundation by scleiHlflc men. J. B. STEERE, Com. Notes, by Kmil Baur, taken at the American Pomological Society meeting at Grand Rapids. E. Moody & Sons, of Lockport, N. Y., have a wagon with a large tank. The motion of the wheel moves the pump to spray the trees. First application waen blossoms are off, then you kill the whole generatlon of codlin moths. Second npplicatlou for later uppie trees about May 20lh, whieli kills the spinner, gcoineter or cankerworm. Gen. Partridge, of Bay City, has a 100gallon tank on a plank wagon with pump on the back of it. For 1,000 trees from 5 to 6 tanks. One-half pound of Paris green for 100 gallons of rainwater. Stiring necessary. London purple dissolves best in warm water. Table spoon of London purple in palé oí water does not hurt domestic animáis. For licc, use whaleoil; tor cabbage worm, pyretrum, one table spoon in bucket water. For curculio use also pyretrum with water or London purple or Paris green. Be careful so that you have no sore on your hand if you use poison. Some use kerosene with soft soap. One quart of soft soap, on gallon of water, one pint of kerosene or gasoline. Heat tlie water. J. D. Baldwin : London purple s far the best. Shaking plum trees BMcUaa and too costly. Spray the trees now, best after a rain. Committee on fruit packages being absent, L. C. Palmer of Dexter, wat called upon to report. Mr. Palmer had acrate with berry baskets which he manufactures at $6.00 per 1,000 delivered at Ann Arbor, they lit the Koohester crates. He will go into inanufacturlng of fruit packages and crates as soon as he finds the needs of fruit growers.
