 be broken into a fine spray and for large trees few nozzles can give the 

 necessary force, and at the same time the mistlike spray that is so desir- 

 able. The Vermorel nozzle works well upon low plants, and if the mixture 

 has been carfnlly strained the graduating spray nozzles will do fair work 

 upon large trees. In case they become clogged, however, it is some 

 trouble to clear them. A nozzle is now sold at $2.00, by John J. McGowen, 

 of Forest Home, N. Y., that seems to satisfy the required conditions, and 

 after a thorough trial it is highly recommended by the officers of the Cor- 

 nell experiment station. 



In April, 1892, a bulletin upon insecticides and fungicides was issued. 

 It contained descriptions and illustrations of many of the more injurious 

 fungi, and formulae for the preparation of a considerable number of 

 insecticdes not mentioned here. A second edition of that bulletin, 

 (No. 88) was printed several months ago and copies will be sent to all 

 applicants who desire more extended information than is given here.
