Eor the purpose of keeping themanure wet, it is best to have a small cistern close to the platform anda pump so placed that the watering of the manure heap is easily ac-complished. If the liquid manure from the stables is conducted bydrains to the cistern, the valuable plant food which it contains willthus be added to the manure on the maggot trap. Experiments have 22 /XS/CCTS AXD />/S/:.lS/:. Fig. 12, TRAP FOR THE DESTRUCTION OF FLY LARV/Ei Maggot Trap) 23 AMERICAN MUSEUM GUIDE LEAFLETS shown that the maggot trap will destroy 99 per cent, of the maggotsdeveloping in manure. After the manure has been standing onthe maggot trap for 10 days it will be practically free from maggotsand may be used on fields or gardens or stored in heaps withoutlikelihood of any further breeding taking place in it. The advantagesof the maggot trap are that it is cheap, requires little extra labor tooperate and to dispose of the drowned maggots, and it does not lessenthe value of the manure but rather tends to preserve it. As is thecase with all other methods, the use of the maggot trap must be sup-plemented by careful attention to possible breeding places other thanhorse manure. 2. Destruction of Adult Flies Simple and effective flytraps may be used to some advantage indecreasing the number of flies. Their use has been advocated notonly because of their immediate results, but becau
