all the ventilators open and with the cooking apparatus at work ; 

 this also forming a test as to the efficiency of the latter. The 

 following Table shows the time occupied in boiling water, also 

 the temperature of the van at the beginning of the experiment, 

 and the temperature at the close of the same, also the increase in 

 temperature during the experiment : —

It will therefore be seen from the above Table that Aveling 

 and Porter were most successful as to the time occupied in boiling 

 the water, which speaks well for the efficiency of the cooking 

 apparatus. Fowler and Co. and M. Faulkes were about equal 

 in this respect. 



The increase in temperature was least in Faulkes's van, although 

 it was closed eight minutes longer than Aveling's van, which 

 proves that Faulkes's van possesses decidedly the best controllable 

 ventilation of the three, and would be altogether superior in 

 this respect, were it provided with some means of ventilation 

 uncontrollable by the men. 



The vans Avere now weighed — first the fore wheels and then 

 the hind wheels being placed on the scales — and we shall see 

 from the annexed Table that Faulkes's van weighs only 50 cwts. 

 2 qrs. 8 lbs., while Fowler's weighs 60 cwts. 2 qrs. 18 lbs., and 

 Avelinff's weisrhs 61 cwts. We also notice that in Fowler's van a 

 greater proportion of the weight is thrown upon the hind wheels. 



Each van was then loaded with 6 cwt. and their draught tested 

 on the hard road by the dynamometer, and we shall see from 

 the Table that Fowler's had the lowest number of pounds of 

 mean draught per gross load, — 103 • 6 lbs., while Aveling's had 

 115 '5 lbs., and Faulkes's 115' 7 lbs. 



The other points taken into consideration Avere the sleeping 

 accommodation, the convenience for cooking and storing victuals, 

 •ground space of the van, strength of frame and general construc- 

 tion, all of which will be noticed in the following descriptions : — 



No. 992. John Fowler and Co. of Leeds. — This van contains five beds, a, 

 one of these being placed against the side in each corner, and the fifth above,
