266 CACAO 



Cases should not be built too large, and should be 

 prepared for such transit as they may meet ; and care 

 should be taken prior to despatch to ascertain what they 

 are likely to meet. It is not intended that a case should 

 be turned upside down, but this may happen on a journey, 

 and therefore all well-packed cases should be cleated in the 

 inside sufficiently well to allow of their being turned up 

 without damage. 



The ship's charges are less for cases Figs. 63 and 64, as 

 the measurement is taken as square from the highest point, 

 as per dotted line, and from this it will be seen that, 

 although the best case for transport. Fig. 62 is also the 

 most expensive for freight. 



Sufficient ventilation should be provided for each case, 

 but, at the same time, too much will damage the contents. 

 For a ease of the most useful size, the dimensions are : 

 Length, 38 in., width 26 in., with gable aS per Fig. 62, 

 and for this, the ventilation should consist of an aperture 

 of 1^ in. diameter high up in each gable. This should be 

 covered on the outside with a piece of perforated zinc or 

 netting to exclude mice and rats, and on the inside it 

 should be covered with a hollowed wooden shield, closed 

 at the top, but allowing passage for the air to the aperture 

 from the base ; this should be at least 4 in. in length, 

 and should be screwed on the inside. This prevents direct 

 currents of air either entering or leaving the case, but 

 provides a slow, suitable, and continuous current, which 

 will avoid damage to the contents if the cases happen to 

 get placed directly in the sun. If left without ventilation 

 in such circumstances the plants would suffer badly from 

 scalding. It may, however, be stated that Wardian cases 

 are always better placed " 'tween decks " than on the open 

 deck. The most suitable place is near an open hatchway, 

 which allows light to enter daily, as a rule. A label notice 

 on the cases to this effect will generally secure such a 

 position from the ship's officers. Instructions should also 

 be placed on each package asking that, in case of breakage 

 of glass, the breakage may be mended by covering with a
