Circassian, Mcaragua, T^onette Lausanne, Red Club, Russian Red- 

 Bearded, and White Club. Forty-fiv(» per cent of the early v^arieties and 

 G7 per cent of the late varieties were badly infested. " Sixty per cent of 

 the early varieties gave fair or good crops in spite of the flies, while 

 only 37 of the late varieties did so." Observations with reference to the 

 relations of early and late planting to injury by the fly indicate that no 

 rule can be laid down on this matter. 



The use of gases against scale insects, F. W. Morse (j)p. 

 319-326). — A summary of information on this subject collated from the 

 reports of experiments by the author in 1887 and 1888, published in 

 Bulletins l^os. 71, 73, and 79 of the station. 



Financial statement (p. 329). — This is for the fiscal year ending

Connecticut State Station, Bulletin No. 110, December, 1891 (pp. 12). 



The bulletin includes an article on Canada ashes and a request for 

 samples of Indian corn. The station desires to make a collection of 

 the varieties of Indian corn which have been grown in Connecticut for 

 a term of years and of new varieties which are considered valuable. 



Canada ashes (pp. 2-8). — Analyses are given of 13 samples of 

 unleached Canada ashes sent to the station for examination. Remarks 

 are made on the sampling of ashes and on substitutes for unleached 

 ashes. 



It is safe to say tliat the carbonates and phosphates of potash, magnesia, and lime 

 constitute the entire agricultural value of ashes. Can we, then, provide 110 pounds 

 of potash, 39 of phosphoric acid, and 1,220 of carbonate of lime in hue condition in 

 some other form cheaper than ashes ? 



An application in the late fall of 20 bushels of burned oyster-shell lime (40 pounds 

 to the bushel), at 12 cents per bushel, would supply as much lime as a ton of ashes at a 

 cost of $2.40; 500 jtouuds of cotton-hull ashes ia addition would cost $8.75 and supply 

 as much or more jjotash than a ton of Canada ashes and very considerably more 

 phosphoric acid. The weight of these two things would be 1,300 pounds as against 

 2,000 pounds of Canada ashes, which involves a saving in cartage; the cost $11.15, a 

 little less than Canada ashes cost on the average. 



The comparison is here made with ashes of excellent quality. With ashes of lower 

 grade, which are more common in our markets to-day, the showing for the substitute 

 would be much more favorable. 



If cotton-hull ashes are not available, in their place may be used 220 pounds of 

 high-grade sulphate of potash and 150 pounds of some cheap steamed bone, like 

 Peter Cooper's Bone, and 800 pounds of oyster-shell lime, the three costing $11.10. 



The above-named mixtures would be close imitations of superior wood ashes, not 

 only as respects tlie kinds and proportions of fertilizing elements, but also as to the 

 forms or combinations of these elements. Still cheaper, and in most cases probably 

 no less effective, would be a mixture of 800 pounds (20 bushels) of burned oyster- 

 shell lime with 150 pounds of Peter Cooper's Bone and 220 pounds of muriate of pot- 

 ash, the total weighing 1,170 pounds and costing $9.45. 



The oyster-shell lime being caustic should be put on in the late fall or early spring, 

 and being fine and pulverulent it will soon be converted into carbonate. 



Stone lime could be used instead of oyster-shell lime, but being in hard lumps
