lecture, either by furnishing a topic, or obtaining specimens. One 

 brought eggs of the Bot fly, which he had secured from one of the farm- 

 horses. Another got Fluke from the liver of a sheep. Regarding their 

 *■ finds " the discoverers asked for information, which is always given. 

 Both these topics served in their turn for lectures and essays, when the 

 respective life stories of these two widely different pests were worked out. 



Tn viticulture the complex life history of Phylloxera is taken as one of 

 our important topics. Either the microscope or the micro-attachment of 

 the lantern is used to display the various stages — all of which from the 

 winter egg to the winged insect, are shown from original specimens. 

 Other in.sect pests of the vine, e.g.. Cut-worms, White Ants, Vine Moths, 

 &c., are similarly dealt with. 



The structure and special qualities of the different American vines and 

 their hybrids, as well as the physiologv of the graft, are particularly 

 studied and illnstratrd 1)V an origina.l and unique set of micro-slides.

Fungus diseases are dealt with in a similar manner. Actual specimens 

 are invariably used in the lecture room, and thus faniiliaritv Avith their 

 appearance, as well as a knowledge of their effects and treatment in the 

 vineyard, are both secured. A strong point is made of taking for each 

 lecture some sea.sonable subject. Erinose formed the theme of an evening's 

 instruction very soon after its discovery in our State. So fungus diseases 

 and insect pests are dealt with as thev appear, and the various agricultural 

 and viticultural practices are discussed as thev are being carried out in 

 the field. 



To imderstand the growth of crops some idea of plailt life is neces- 

 sary. Agricultural botairy is treated in a practical, and as far as possible 

 in a popular manner so that facts are learned without burdensome 

 phraseology. Root structure, and the methods by which a plant obtains 

 its food and grows, are studied and the necessity of securing pure, clean 

 and good seed is demonstrated. In economic entomology the same 

 methods are adopted. Specimens are secured. Their life history and
