The Colorado potato beetles were very numerous iu the early part of the season, 

 which made it necessary to spray the vines often; but the late varieties were 

 sprayed only when they were about four inches hig-h and Avhen half grown. For 

 this purpose white arsenic instead of Paris green was used with good results. 

 Great care, however, must be taken in the use of arsenic, or the foliage will be in- 

 jured. It should be prepared as follows: For one pound of arsenic, take two 

 pounds of unslaked lime, and two gallons of water. Slake the lime in the water and 

 heat until it comes to the boiling point; then add the arsenic and let it boil slowly 

 for thirty minues. The arsenic will dissolve and unite with the lime, forming an 

 insoluble compound, which can be used without danger of injuring the foliage, at 

 the rate of 200 gallons of water for one pound of arsenic. Bordeaux mixtiu-e was 

 also applied to the entire crop as a preventive against leaf blight. 



In addition to using the more promising of the varieties tested in 1897, an en- 

 deavor was made to secure new varieties from seedsmen anu introducers. The 

 addresses of the seedmen from whom the new varieties were received are as fol-

Notes on New Varieties. 



Clinton.— A medium late kind which appears to be productive and in every way 

 promising. The vines are dark green, strong growers, branching close to the ground 

 and exceeding two feet in height. The tubers are medium to large in size; in shape, 

 round, or a little elongated and sligthly flattened; skin, clear white, smooth, finely 

 netted r.ud spotted with numerous small dots; eyes, long, broad and shallow, 

 slightly lipped. The texture is firm, white and floury. 



Dawn.— An early variety that resembles Early Ohio in growth, but is a little 

 different in form. The vines are also more slender than those of the Ohio. The
