We would say that the station is in good condition; all trees and shrubbery have done well; no complaint as far as growth is concerned. This being an off year for fruit in this section, the fruit crop in general was light, the late frost and heavy rains destroying most all, both wild and tame fruits.

The strawberries, raspberries and currants were fairly good; plums and apples were very light, except some seedlings, both apples and plums, which seemed to hold their fruit. Most all the large apples were destroyed by the freeze, such as Duchess, Wealthy, Greening and Hibernal. There were some of the Duchess seedlings that seemed to stand all kinds of freezing.

Now in regard to the fruits that were sent here from Central station. The majority are doing fairly well, especially in regard to strawberry No. 3, which is doing splendidly and points to be the coming strawberry of northern Minnesota. It is a good runner and has a large, dark foliage. Plants that we left out last winter without covering came through in splendid condition and made a heavy crop. In regard to the fruit, it is of the best quality, large and firm and a good keeper. In regard to raspberries, Nos. 1, 4 and 7 did very well, and stood the winter without laying down, and bore a good crop.

In regard to the eighteen plum trees I received three years ago, Nos. 1, 4, 5, 6, 7, and 12 have done very well and have made a good growth, but have had no fruit so far.

The sand cherry that was received the same year, No. 2, has done very well and bore some fruit this last year of a fair quality.

Hansen cherries are doing fairly well and bore some fruit this year.

Now in regard to plums that were received in 1914 Nos. 2, 3, 8, 10, 13, 20, have all made a good growth. What was received in 1915 have all grown.

The grapes that we received two years ago have made but little growth. There were no grapes in this section this year; they all froze off about twice.

I received at the county fair about sixteen first prizes on apples and plums this year. We did considerable top-working, mostly on Hibernals and native seedlings, which are doing very well. Some of our seedling cherries are commencing to bear and show to be perfectly hardy. They are of the Oregon strain of sweet cherry.

In regard to gardens, they were fairly good throughout the section. Corn crop a failure.

In regard to the condition of the trees and shrubbery, this are going into their winter quarters with lots of moisture and with a large amount of fruit buds, with a good prospect for fruit next year.

Destroying Plant Lice.—According to the results of experiments a 10 per cent kerosene emulsion should prove effective against the green apple aphis. The kerosene emulsion made either with 66 per cent stock, 10 per cent, or with naphtha soap and cold water, seemed to kill all the green apple aphides. The 40 per cent nicotine solution, with a dilution up to 1 to 2,000 combined with soap, were likewise effective aphidicides. The kerosene emulsions under 10 per cent were not satisfactory, neither were the soaps at the strengths tested, except that fish-oil soap, 5 to 50, killed 90 per cent of the aphides. Laundry soap, 3 to 50, was effective against the young aphides only. Arsenate of lead alone, as was to be expected, had little or no effect upon the aphides. The combination of arsenate of calcium with kerosene emulsions is not a desirable one, since an insoluble calcium soap is formed, thereby releasing some free kerosene.—U. S. Dpt. of Agri.
