WISCONSIN HORTICULTURE STOCK SOLUTION OF LEAD ARSENATE Prof. Watkins of the Illinois Uni- versity offers a very valuable sugges- tion in the way of a stock solution of lead arsenate as follows: Although arsenate of lead has many good points in its favor as an insec- ticide, it is for from being an ideal product. Arsenate of lead which hais dried out and become hard is quite difficult to mix again with water, and is not as easily kept in suspension during the process of spraying. Inl order to avoid this, manufacturers as a rule have sold a product which is about 50 per cent water. 'T'his has led to some dissatisfaction, since dur- ing transportation the paste has lo-t water through evaporation, the pack- age not being air-tight. If we were to weigh the contents of the package as soon as received, we would in all probability find it to weigh son1m, what less than it did when leaving the factory, so even if we use the material as received one time we may be using a third more arsenate than at others, owing to the degree of evap- oration which has taken place. Also, if a package is opened early in the season, a small amount taken out and used, the balance protected in nio way from evaporation, it is quite pos- sible that four pounds of the paste at the close of the season will represent five or even six pounds of it as it left the factory. This is almost a total loss since many experimenters claim two pounds per fifty gallons to be as effective as when three or even more are used, and if fifty pounds are purchased, with the expectation of using it as recommended by the fac- tory, it will be found to fall short of that weight if means are not taken to prevent evaporation. Why not avoid all of this by preparing a stock solution of arsenate of lead as fol- lows: Before it is time to use the arsenate, take the contents of a 100 pound package, put it in a fifty gal- lon barrel and work the whole mass into a thin paste; when this is ac- complished add enough water to make the paste up to fifty gallons, then there will be a stock solution, two pounds in each gallon. But, better than that we need a powdered arsen- ate, then we will avoid paying freight on fifty pounds t of water every time fifty pounds of arsenate of lead are pit rehiased, and also be saved the, trouble of working the thick paste io- to it thin one. Attention is called to the powdered form since it is a ,tep ini the right direction, and if the crst of it (ldos not prove prohibitive, I Ibe- lieve the solution has been solved. since in every other way it gives as perfect satisfaction as paste formo. THE OLD STRAWBERRY BED Experieneid lerry growers wilI please turn their face-s to the wall anid take a nap, this little sernion is only for the beginner. A strawberry bed will bear wivll for at least ftur seasons if itropterly treat- ed after fruititig. If your bed is like most litte gr- den beds it is merely a unat of vines covering the ground completely ex- cept holes here and there that yit iiade with your feet in picking. Per- haps it is not quite as bad as this. irerhaps you have thickly matted rows of plants about two feet wide and paths between. fn either ease we want to get rid oif bitmi 95 per cent of the old bell and provide for a crop of new plants. If you have the first kind of a bed dscrihed above select strips of plants ronning through the bed each about eight inches wide, three ant a half feet apart and cut out everythintg else. These strips or rows shoulh be outlined with garden line and stakes hefore beginning, then with a sharp hoe or spade slice off everything out- side of the lines. Next remove and burn the plants and weeds, cut out and spade spaces between rows. Last of all go over the plant rows left for renewal, clean out all weeds and grass and also about one-half of the plant-. leaving them ahlout one foot apart and the remainder ought to send out rimners enough to furnish a gootd set for next year. Keep bed clean auth cultivate uiitil ground freezes. If your led is iin rows select yo,, renewal strip just alongside of the original row so as to get only miw year old plants for retvewal. FOR THE BEGINNER Tle stiawherry plants in the miev' ly set bed lutist not be allowed t, hItve their own sweet way.
