ing to the followmg formula : soda, i pound (a pound can of 

 Lewis' Lye, for example) ; copper sulphate, 3 pounds ; lime, 5 



ounces ; water, 30 gallons. 



In order to prevent the mixture turning brown (which does 

 not, however, lessen its efficiency but discolors the treated plant) 

 a small quantity of lime is used to neutralize any excess of acid 

 and in this way a permanent bluish-colored solution is obtained. 

 The advantage claimed for this combination is the absence of the 

 large amount of the lime in the ordinary Bordeaux mixture, and 

 it may prove of considerable value in spraying in the fruit garden 

 and vineyard, in particular when the fruit is nearing full size and a 

 clear fungicide does not leave a serious stain upon the fruit. The 

 ease with which the compound may be made and the absence of' 

 any danger of clogging the spraying machine commend the mix- 

 ture to the practical mind.

Four varieties of bush 



beans were under experimentation the present season, namely the 

 " Green Flagolet," " Golden Wax," " Early Refugee" and 

 " Saddleback Wax." Two plots were employed, one of them 

 having been in beans continuously since the spring of 1894, two 

 crops'' each year, and therefore the present season produced the 

 ninth and tenth successive crops. The other plot was of land that 

 had not been in beans for many years, if ever before. Upon the 

 old land the " Refugee" proved the most productive and the 

 " Flagolet" the least, but In spotted pods the results were reversed. 



The new land carried a duplicate of the experiment of the one 

 upon the old land, and here the " Refugee" proved the most pro- 

 ductive and least susceptible to the disease. If one were seeking 

 a variety to furnish an abundance of disease, for experimental pur- 

 poses, he could scarcely go amiss In .selecting the "Flagolet," 

 while, on the other hand, the "Refugee" would be less acceptable. 

 In foliage the " Flagolet" is exceedingly tender, and from the time 

 the first true leaf appears there Is more or less blight in sight. 



With the second or autumn crop the same record is made, 

 namely that the " Flagolet" leads all other varieties in suscepti- 

 bility to the blight. From this and the experience of other years 

 this sort may be considered as one of weak resistant power.
