they are kept isolated there shoiihi be no loss from blackhead. 

 In case the disease appears, it should be assumed that they 

 are getting worm eggs from the soil upon which they are con- 

 fined, and steps should be taken immediately to move the 

 yard to new land. With regard 'to the isolation of sick turkeys 

 from the rest of the flock, this is proper as far as it goes, but 

 it should be borne in mind that other sources of worm eggs are 

 fully as important. 



Protection from Intestinal Worms and Other Parasites. — The 

 sudden acquisition of large numbers of the parasitic worm, 

 Ileterakis papillosa, commonly found in common fowls and 

 turkeys, is extremely likely to be followed by blackhead. How, 

 then, is this to be avoided? The giving of vermifuges from 

 time to time will not insure against the acquisition of w'orms 

 in the interval, for the eggs of the latter may be picked up at 

 almost any time. It is necessary, therefore, to depend upon 

 isolation. If turkeys are raised upon a place where no other 

 poultry has been kept, isolation is a simple problem. It is 

 then only necessary to keep the young turkeys entirely apart 

 from the old ones, and never allow them on ground ranged 

 over by the latter. In case poultry is kept upon the premises 

 the problem is much more difficult, especially if it is allowed 

 free range. It will then be necessary to keep the growing 

 turkeys yarded on clean ground at a distance from the poultry. 

 This makes their supervision more difficult, and the expense of 

 fencing an enclosure large enough to provide forage throughout 

 the season is likely to be considerable. Such isolation will 

 probably not serve to prevent turkeys getting an occasional 

 worm, but they are apparently able to take care of a small 

 number of these w^ithout getting blackhead. The eggs of these 

 worms are quite resistant, and are probably transported from 

 place to place by sparrows and other birds visiting hen yards, 

 and possibly, to some extent, by the flies that feed upon the 

 droppings. If hens are kept, care must be taken that the 

 droppings of the henyard are not carried into the turkey en- 

 closure on the shoes of the attendant. The rule of always 

 tending the turkeys first, and then the hens, is important. 



Young turkeys should be kept away from other poultry until 

 they are ready for market. Although few large turkeys sue-
