there Is the die dis tg task of releasing the dead all by hand band which naturally la Is in spite of or the fact that at season of the year tho the major portion of the country is undergoing what seems to the residents like tropical heat there are many localities where the nights are sufficiently cold to warrant the building ot of a fire in the grate in rooms which are provided with them ai these grates and fire places are not ts Is common as one might wish for recourse may be had to the heat gen elator shown in the accompanying drawing which Is the idea of geore george S chase of springfield mass the invention Is practically a radiator which gathers up the rising heat rays from rom the flame name of the lamp and distributes them about the room instead cf of allowing them to rise vertically to the telling the circulation of this heated air also produces a current which draws the air from the room ind and brings it in contact with the hot surface of the generator thus further increasing the generation of warm arm r the generator is built up of a teries series of thin metal plates with an opening at the bottom for the insertion of the lamp chimney it Is supported by a vertical post and project toe ing arm the latter being hinged to any ono one boti of the above objections are overcome in the trap shown tn in tho the accompanying drawing the invention of joseph chagnot of torrington conn the device consists of 0 a water two bait holders and a tilt ing int platform the primary bait holder is located above the inclined run 1 way and the second holder over the tilting platform in use the animal finding it difficult to get the bait from the primary bolder holder will move forward and attempt to obtain the second morsel in so doing he wilt will pass be yond the pivoted point ot of the tilting platform and his weight will cause it to tilt and will precipitate him into the reservoir here the death penalty Is inflicted the platform im mediately med lately

post a lamp of any r size can be used and as there Is no connection between the eb amney and the ge generator the lamp can be b in scantly removed if oc caslo casto requires rec captive Bal balloon loori observatory Observe tory going up in a balloon Is a feat that the majority of leonle do not care to perform but if tho balloon were capote with no chance for it to escape tt it would make little difference at v ahat hat height it was anchored the higher up it was the greater would be the temp tation to ascend and view the scenery the intention of the inventor Is to provide a car of sufficient buoyancy to carry cables of great length with means for drawing the balloon down to anchor it close to the ground when not in use the gas reservoir Is divided antu sections with an equal amount of gas in each and in case of puncture in one of the sections tho the remaining pockets would have dent clent buoyancy to support the car un til repairs could be made it Is already common practice to at tach a balloon to a single cable wound on a drum and alow a 4 few persons to ascend at a time tut the amount of power required Is much greate than that to raise the elevator in this case there Is a central opening in the observation vailon platform through which the car rises to discharge and tako take on passengers I 1 ith a single bablo to opar tc te the car joseph greth of new york Is 1 the in debtor
