    Notes: Survey data collected during a grassland-recording investigation showed a strong positive correlation between nitrogen input and the output of utilized starch equivalent per acre. At the levels of output covered, sward type was not very important in relation to total yield. Herbage species were important for other reasons and the choice of seeds mixtures should be determined by factors such as earliness and lateness of growth and resistance to disease and drought. The survey showed that well-managed ley and permanent pasture are both capable of producing at a high level. A disturbing feature of the results was the low production of most spring resowings, primarily as a result of poor management. Although the records were obtained from an above-average group of farms, the results have general application. Potential responses to fertilizers may be even greater on less intensive farms, especially with regard to phosphate and potash. However, the level of production of a field will always depend finally on the level of management exercised by the farmer himself.

    Notes: Swards based on a mixture of SI 70 tall fescue and S215 meadow fescue were very early in spring, gave high yields for conservation in mid-season and, rested from mid-August, gave good grazing in November-December. Under this treatment, the tall fescue assumed dominance, and the swards were persistent and remained productive. The digestibility of the tall fescue swards was always higher than that of swards based on cocksfoot with which they were compared. During spring and autumn the former sward was better grazed by stock, but the position was reversed in mid-summer. Cattle grazing tall-fescue-dominant swards made better liveweight gains than those grazing cocksfoot swards during November-December.

    Notes: The value of varieties of Italian, hybrid and Westerwold ryegrass for early-bite production was compared at 32 centres in different environments. The relative performance of Italian ryegrass varieties was fairly consistent from centre to centre over a period of 3 years. Danish and Leda Daehnfeldt Italians produced the most, and S22 the least, early spring production. Good early-bite and total annual yields were obtained from hybrid ryegrasses. Swards sown in the previous autumn were more winter-hardy than spring-sown swards and appeared to be as early in the following year.

    Notes: One hundred and fifty wines of different types and regions were scored by 11 experienced judges by two methods (scoring and comparative rating). It was thought that the second method (which included a reference wine) would give more stable and consistent results than the standard method. For some categories of wines the standard method resulted in more stable and consistent responses, but for other categories the reverse is true. For some judges and for some categories of wines the two methods were practically identical. The reactions of the judges to the two methods varied greatly.

    Notes: A study was made to see if the exterior structures of the egg (cuticle, shell, and shell membranes) can support the growth of bacteria. Two species of common egg-spoiling bacteria and a pathogenic bacterium were examined. The exterior structures supported extensive growth of all three organisms comparable to that found when the same bacteria were cultured in albumen. When these bacteria were seeded into sterile saline containing intact egg shells, they could he isolated, after some time, from the inside of the shell.

    Notes: Duck eggs were the most susceptible to bacterial spoilage, and turkey eggs were at least as resistant as chicken eggs and in some experiments appeared significantly more resistant. Under storage for 6 weeks at room temperature, however, the ability to resist bacteria was essentially unchanged in duck eggs and very markedly lowered in chicken eggs. Similarly, duck eggs lost very little quality (Haugh units) upon prolonged storage, and chicken eggs lost interior quality much faster. Bacterial penetration studies of chicken and duck exterior structures with model systems demonstrated that the outer shell membrane was the least resistant, followed by the shell and then the inner shell membrane. No consistent or significant differences in bacterial penetration were found between chicken and duck eggs, although the inner shell membrane of the former was thicker than that of the latter. Egg albumen was implicated as a major barrier to bacterial egg spoilage; conalbumin was an important inhibitor in egg white.

    Notes: Summary Tomato plants were cultured at various levels of rubidium and potassium in water culture. Growth as measured by dry-weight accumulation was reduced by the substitution of rubidium for potassium. The reduction in root growth was greater than the reduction in top growth; therefore, increased shoot/root values were noted with increasing rubidium concentration. In other experiments the potassium and rubidium content of the root and aerial portions were determined. It was found that rubidium tended to accumulate in the roots rather than the tops; it is postulated that this accumulation may be responsible for the observed inhibition of root growth. Potassium concentrations were similar in both the roots and tops indicating that the two cations did not behave similarly in these experiments.

    Notes: The motion of individual air bubbles in a water stream flowing turbulently in a 4 in. × 4 in. vertical conduit is investigated by photographic means. The bulk water velocity ranges from 40.8 to 267 cm./sec., corresponding to a system Reynolds number range of 48,600 to 386,000. Both tap and demineralized water were used at or near room temperatures. Air bubbles range from 0.038 to 0.70 cm. in equivalent radius and the corresponding bubble Reynolds number based on relative velocity ranges from 58 to 4,500.The results indicated that the bubble relative velocity in a turbulent water stream is similar to the rise velocity of single bubbles through a quiescent liquid. It was found to be practically independent of the system Reynolds number for bubbles having an equivalent radius above 0.3 cm. Large fluctuations in the bubble velocities were noted in all cases. The drag coefficient is, in general, lower for the demineralized water tests than for tap water when the bubble Reynolds number is below 2,000. Above this value, a mergence of the drag coefficients for all tests occur with a peak of approximately 2.0 at a bubble Reynolds number of 3,000, which is lower than the nonflow value of 2.6.
