It is evident that the rise of temperature will be most rapid 

 under clothing which has a maximum capacity for heat absorp- 

 tion and a minimum capacity for circulation of air to allow for 

 the evaporation of moisture. Clothing which, in the sun, will 

 cast a shade upon the body without hindering the air circulation 

 and heat radiation will be the most desirable, and if a color is 

 used which will give a minimum of heat absorption, the efficiency 

 is increased. This ideal condition is fulfilled by the umbrella, 

 and it is evident that a large, white umbrella lined with a ma- 

 terial of a color agreeable to the eyes, for example a shade of 

 green, will be the most efficient. The more nearly this condition 

 of clothing is approached, the more comfortable will the subject 

 be in the sun and the better prepared to withstand its evil effects. 

 In the case of the foreigner, it is manifestly impossible to meet 

 these requirements, but in the case of the native it is astonishing 

 how closely he has instinctively, or otherwise, adopted this form 

 of protection. The native hat woven from a variety of materials 

 and called the salacot is a common sight in the country and it 

 is often seen in the cities. It is arranged so that the crown is 

 supported some distance above the head and is so large, often 

 nearly a meter in diameter, that the wearer is thrown completely
