effected by a small ammonia compression plant at the end 
of the car. 
An English insulated motor van has a carrying capacity 
of about 4} tons of meat, either in the form of 45 quarters of 
beef or 200 carcases of mutton. 
An insulated meat barge on the Thames is about 8o ft. 
long by 19 ft. 6 ins. beam. The insulated hold is about 
48 ft. by 16 ft. The capacity is about 64 tons dead- 
weight. The insulation consists of cork slabs and waterproof 
paper, 
PRE-COOLING. 
A very necessary precaution to adopt is to thoroughly 
cool the cars before anv meat is placed in them. This cannot 
be too much insist -~<n. The following remarks upon 
the matter ~~ "7 * Woods * may appropriately be

*“ Pre-cooling is the basis of success of all transportation 
of refrigerated produce, cither when being transported to 
the seaboard prior to shipment, or when in transit from the 
ship’s side to markets and stores, by horse van, motor van, 
railway car, and barges. The work of pre-cooling prepares 
the chamber of vehicle to receive its charge or consignment, 
in so doing prevents greatly any rise in temperature while 
loading, and the goods to maintain the temperature for 
a much longer period, thus enabling them to be sent 
a greater distance. 
“In this country, if the system of pre-cooling was univer- 
sally adopted, and insisted on, and an efficiently insulated 
car provided, then the question of icing the car would be 
quite a secondary consideration, except in the very hot 
weather, when icing would be needful. 
“In America, many experiments of pre-cooling have been 
tested, and the results have been most satisfactory. To 
illustrate what efficiency can be arrived at, when a properly 
insulated car is used, same being first pre-cooled, as also
