sent to sea, and when not less than forty miles from land 

 cleaning operations should begin on the lowest occupied 

 deck, the whole of the solid excreta, fodder, and fittings 

 being brought up and thrown overboard. The steam pump 

 is now turned on, and every portion of the ship's side and 

 decks thoroughly washed down, not a place must be 

 omitted. The other decks should be dealt with on identical 

 lines, the most thorough and prolonged flushing being 

 given. The bilge should be pumped out, and disinfected 

 with carbolic acid. 



In this way it is assumed that everything in contact with 

 the animals capable of being destroyed has been thrown 

 overboard, and the decks and sides of the ship thoroughly 

 washed. The place is now ready for disinfection either 

 with carbolic acid, chloride of lime or Izal, and again the 

 spraying process previously described may be introduced, 

 every corner, nook, and cranny being searched with the jet. 

 The ship may then be put back to port, and the disinfection 

 repeated in two days' time. Painting is advisable, and the 

 vessel is then free to carry another cargo. (See also Transit 

 of Animals.)* 



Dismfection of Hides, Harness, and Hoofs. — This may be 

 obtained by placing them in large vessels containing 

 sufficient disinfectant, where they are to remain several 

 hours. This disinfection only applies to the offal of the 

 incontacts, that belonging to the affected animal is 

 destroyed, if possible by fire. 



Cremation. — The destruction of diseased animals and 

 their excreta is best done by fire. It is a costly process 

 but absolutely satisfactory, and is time saving compared 

 with the labour of digging deep trenches for the reception 

 of bodies. 



Field cremation is easily carried out. Nothing is required 

 but a trench dug in the ground in the shape of a+ (Fig. 171). 

 Each trench is 7 feet long, about 15 inches wide, and 18 



* At ports in Great Britain which are specially told off for the 

 landing of foreign animals, all facilities exist for dealing with infected 

 cargoes and ships.
