70 American Horticultural Society. 



Whkreas, The people of Louisville, Kentucky, have by private eontributious 

 prepared extensive buildings and grounds suitable for the purpose in view, and 

 propose to hold therein a national agricultural, horticultural, mineral, timber, 

 and live-stock exhibition, illustrating the agricultural and horticultural features 

 and natural resoiirei's of America; and, 



WiiKKEAS, It is desirable to aid and encourage an enterprise so beneficial to the 

 people at large ; therefore, 



Be it Resolved by the American Horticultural Society, now in session at New- 

 Orleans, La., this 16th day of January, 1885, that this Association api)roves 

 the plan for such an exhibition set forth in the prospectus of the Southern Exposi- 

 tion at Louisville, Ky., dated October 23, 1884, and signed by the general commit- 

 tee of said company, and the bill in Congress to encourage the holding of said 

 exhibition, introduced by the Hon. A. S. Willis of the House of Representatives, 

 and hereby memorializes Congress to enact said bill and make the appnjprialions 

 therein stated, with such regulations in regard thereto as Congress may in its wis-

Be it further Resolved, That this Association extends to said enterprise its cordial 

 support, and hereby offers to cooperate with the managers of the same in making 

 the proposed exhibition a complete and full illustration of the horticultural in- 

 terest and industries of America.

 luittee of five for further consideration. 



Dr. C. V. Riley, U. S. Entomologist, Washington, D. C, was 

 then introduced and delivered an interesting verbal address on

WITH SUGGESTIONS FOR COOPERATION IN FURTHER STUDY AND EXPERIMENT 



WITH the:m. 



[Prof. Riley's address created intense interest because of the many important 

 practical suggestions which it contained. But it was verbal, and to a large extent 

 an explanation of appliances brought for exhibition. The report of his remarks 

 is therefore necessarily incomplete, and I regret that he has been unable, for want 

 of time, to prepare the report himself.- — Secretary.] 



Dr. Riley said: The recent method of evaporating the oil of tobacco is a 

 most useful mode of using it, where it can be so used. Mere strewing 

 of stems on the ground, where the ground is periodically moistened, is suffi- 

 cient to destroy many insect pests. 



Three suhstances are more practically useful as insecticides — arsenic, 

 pyrethrum and i)etroleum. 



Arsenic is dangerous when used for protecting fruits. He felt averse to 

 recommending it except where there was perfect safety. 



Passing by iiyrethrnni, which is limited in its usefulness, he treated of
