(1) The addition of basic slag to moist base-unsaturated soils, under laboratory conditions, causes an increase in their content of exchangeable calcium, degree of saturation, pH, and the amount of calcium soluble in an aqueous solution of carbon dioxide.(2) Slag seems to be almost as effective as calcium carbonate or lime in increasing the exchangeable calcium and the degree of saturation of soils, but its action on pH is not so marked.(3) The effect of dressings of slag on the lime status of soils from experimental plots is still evident after eight years.(4) The exchangeable calcium of samples of soil taken from the same fields after an interval of six years shows a considerable fall due to leaching.(5) It is suggested that the addition of low grade basic slag to unsaturated soils may tend to maintain or improve their lime status and will, to some extent, compensate for the loss of calcium due to drainage and crops.

Wing Structure

During May, 1957 near Lumby, B.C., there was a reoccurrence of the gregarious flight behaviour of Priacma serrata males observed the preceding year (Atkins, 1957). Once more these beetles exhibited a strong attraction to “Perfex” laundry bleach, which is an aqueous solution containing 5-5.5 per cent sodium hypochlorite and 4.3 per cent sodium chlorate. They swarmed around the bleach-treated articles every fair day from the 5th of May until the first week of June. This situation presented an ideal opportunity to study certain aspects of the behaviour of this strange insect and accordingly observations were made on the beetles' flight both in the field and under laboratory conditions.

The effect of the salt composition of water (model aqueous solutions of NaCl and artificial sea salt Instant Ocean, as well as water from the Pechora Sea) on the effectiveness of oil spill dispersants determined in laboratory conditions is studied. The efficiency of dispersants (Finasol OSR 52, Slickgone NS and Slickgone EW) was evaluated three samples of crude oil produced in the Russian Federation. Those oil samples of different composition and properties were used at fixed values of the dispersant-oil ratio  (1:10), water temperature (20 ± 2°C) and salinity (35 ± 2%). It is shown that the effectiveness of the oil spill disper­sant depends on  the nature (composition) of water in which the oil is dispersed, other things being the same. An anomalous behavior of one of the oil samples was found when it was dispersed in an aqueous so­ lution of NaCl under the action of Finasol OSR 52 and Slickgone EW Good convergence of the numerical values of the efficiency of dispersants was obtained when testing them in an aqueous solution of artificial sea salt Instant Ocean and in the water of the Pechora Sea. It is noted that to assess the effectiveness of dispersants in laboratory conditions, it is advisable to use water of the natural object in which this disper­sant is planned to be used. Moreover, the possibility of using an aqueous solution of the artificial salt when its salt composition is similar to that for real sea water was noted.
