less than 1 foot above the concrete floor in order that the floor may be mora easily cleaned A third point is that old manure does not attract flies for breeding. A lot of manure need remain on the maggot trap but 10 days in order to prevent any breed ing taking place in 1t
 The naggot trap thus presents the great advantages of being easily con structed and cheap. That it is ef-s land Agricultural College have con clusive1y shown There it was found that it destroyed 99 per cent of the larvae breeding in the manure and that the number of flies around the college kitchen was reduced by be- tween s I and ' per cent That the reduction in the number of flies was not equal to the percentage of larvae destroyed was due to the fact that there were other piles of untreated manure elsewhere in the vicinity and that flies bred in these Such traps may be built in almost any size and they appear to be especially we'll adapted for controlling the pest un- der ordinary country conditions
 In cities and towns it is probable that the treatment of manure will heIlebore will usually be found more advantageous. Ten gallons of the so- 1ution already described, composed of 1-2 pound of powdered heIlebore to 10 gallons of water and allowed to stand A hours, will be sufficient for the treatment of bushels or 10 cubic feet of manure. A weaker solution than this is not so effective. The helIebore does not alter the compost tion of the manure in any way and does not cause any injury to crops on which the latter is placed. In fact the only possible way in which it can do any injury upon the farm is in or in rxzI1i i137 I7a solution is stored is left uncovered in a place where some of the farm anil naals may drink from It. The most ordinary care. however, Is sufficient cost of the treatment, with heIlebore selling from 12 to 16 cents a pound and in large lots for 10 cents or Iess is estimated at a little over 1 cent for every 2 bushels
 Borax is perhaps evenI more effec- tive in the killing of larvae than hellebore, but borax has the dfsad- vantage of exerting in large quanh- ties an injurious effect upon plants. It is possible that manure treated with sufficient borax to destroy the larvae and then applied to plants at a greater rate than 1 5 tons per acre may work harm to certain crops. Where borax is used for the preven- ton of f1es. therefore, no mere than pound should be employed for every l 6 cubic feet Of manure and this manure should not be used at greater rate than Is tons to the acre
 This objection to borax, of course, does not apply to it's use on the ground of stables with soil floors, in privies and refuse piles. and on other aeeufnuIahons of decaying r11a- teriaI in which flies may lay their eggs.
 While the use of naagget traps and the tFeatm ent of manure with helIe- bore or borax are most effective in reducing the number of flies, it is not likely that they will actually exter- fflinata the pests in any neigh boFheod. The Preeaution of screening windows and doors and in particular the pre- teeting of all articles of food with f1y-pFeef screens is, therefore, urgent Iy recommend by the DepaPtment of Agriculture. Screening, of course, has ne effect upon the number of flies, but it does naiHiRize the danger of infection. Comparatively few pee pie how admirably adapted from it's strueture and habits the fly is to car Fy disease. The body of the house fly, and especially the legs, are thick ly COW cred with hairs and hristIes. As the fly craw1s about ever the de- eaVfaa organic matter on which it
