288 JOURNAL OP THE TRINIDAD 



" Sacken's specimen came from the Mainland." — Mr. Urich said 

 that when coming down from St. Ann's one dark night he noticed 

 a patch of phosphorescent light of about six inches diameter on a 

 tree near Coblentz. Thinking it might be a jumbi (he was very 

 anxious to catch one) he struck a match and found the light came 

 from part of a deserted termite's nest, no doubt it was caused by 

 decaying vegetable matter or possibly a fungus. He then read 

 the following extract from an article on ants' nests in Brazil by 

 Frederick Knab in the Entomological News. " The termites on 

 " the contrary, live in large irregular conical mounds, hard as 

 " rock and often ten feet or more high. In the day time there 

 " is no sign of life, but if one enters the forest at night, the sight 

 " is a beautiful and startling one — the darkness is intense. Here 

 "and there in the blackness may be seen clusters of glittering 

 " phosphorescent light. These are the Termite hills. No doubt 

 " the light proceeds from the insects as the particles of the light 

 " mass move and change. The light is greenish and soft, and the 

 "effect is indescribable. In marked contrast is the gleaming red 

 " light of the Elaters as they dash rapidly through the foliage." 

 Mr. Urich said the description of the light agreed with his 

 observation, but it did not move and there were no insects in the 

 nest he saw. — On the motion of Professor Carmody it was decided 

 the Club meetings should take place monthly, as formerly, 

 instead of every two months, as had been the case lately. The 

 meeting came to a close at 10 p.m.
