ship and subsequently elected active members. There being no further 

 business, Mr. Henry L. Ward spoke on new methods of mounting 

 museum specimens, and their effect on the educational value of the 

 exhibits. He described the way in which large mammals are mounted 

 on manikins prepared from clay models of the specimens, showing 

 how a mold is taken which later serves to cast the manikin in rein- 

 forced papier mache. This, covered by the skin, forms the mounted 

 mammal. The speaker also showed some of the steps in preparing the 

 birds and assembling them with other accessories in the making of 

 large groups for museums. The making of the accessories was also 

 described. The talk was illustrated by lantern slides made of work 

 done in the Public Museum. 



Mr. C. T. Brues then gave a brief talk on injurious insects in their 

 relation to some of the broader problems of agricultural development 

 in the United States. He dealt with several of the insects which have 

 affected large areas of the country so as to necessitate changes in 

 agricultural procedure, and elimination of certain crops. The Mexican 

 cotton boll-weevil was cited as an instance of the awakening of a new 

 agricultural era for the South, especially as recent discoveries con- 

 cerning the cattle-tick have removed another stumbling block to the 

 development of stock raising in this same region. The Codling Moth, 

 Corn-ear Worm, Hessian Fly and several others were also dealt with in 

 a brief way.

Mr. Herbert Clowes exhibited an enlarged model of a yucca flower 

 and a yucca moth, showing the. peculiar method of pollination of the 

 plant. He described the remarkable interdependence between the yucca 

 plant and the insect which pollinates it, also giving an account of the 

 plant and the insect in detail by means of charts' and lantern slides. 

 Mr. George W. Colles then gave an account of a foot trip taken last 

 summer from Orizaba to Esperanza through the mountains of Mexico, 

 speaking more particularly of the character and vegetation of the 

 country between these places, the latter being at a much higher alti-
