the end of the season the mildew developed but little upon any of 

 the plants. 



One side of a lilac bush was treated with the emulsion August 25tb. 

 and September 10th, without seeming to check the development of 

 the mildew. In this case the mildew was well developed upon the 

 foliage, and the two applications did not materially change the- 

 appearance of the leaves. 



Three places in a large piazza plant of Matrimony vine were sprayed' 

 twice each week with the emulsion, and it seemed to prevent the 

 appearance of the mildew upon the younger leaves, and the fungous- 

 patches upon the old ones were darkened and ceased to form spores. 



Soda-Bnrdeanx and Paris Green. 



To determine whether Paris green may be safely used with soda- 

 bordeaux, the combination was applied to the following plants : 

 Potatoes, eggplants, squashes, cucumbers and beans. 



Each of the above were treated three times, at intervals of ten days 

 and without harmful results, although the Paris green was used at 

 the rate of one pound to 100 gallons, a much higher percentage than- 

 is commonly employed. 



THE ASPARAGUS RUST. 



During the present season it was not convenient to carry on any 

 experiments with the asparagus rust, and only observations in the- 

 field and reports from the various Experiment Stations throughout 

 the United States are given. The rapidity with which this disease 

 has spread has added to the importance of a record of its present 

 range. 



Without reproducing the replies to the letter of inquiry sent out in 

 September, the following extracts will show something of the wide 

 range of the rust and also some points as to its relative abundance 

 with that of last year. 



From New England, where the asparagus is widespread, but gen- 

 erally grown only in limited quantities, the reports show that there is 

 less rust this season. For example, in Professor Jones' report for 

 Vermont, it is stated that " there has been less of the asparagus rust 

 in this State than there was two years or so ago." 



For Massachusetts, Professor Stone writes: "The rust has been 

 prominent here this season and there has been a slight tendency for
