    Notes: Shortly after Julian West awakened to Edward Bellamy's utopian Boston of the year 2000, he was given his first look at the city by his host, Dr. Leete. West nearly fainted at the “ prodigious thing which had befallen me.” Still in a daze, he was asked by Dr. Leete what surprised him most about the new Boston. “ I really think,” West responded, “ that the complete absence of chimneys and their smoke is the detail that first impressed me.” The city, as Bellamy went on to describe it, was an affair of fine buildings set in “ inclosures.” There were “ large open squares filled with trees, among which statues glistened and fountains flashed.” Julian West could see the Charles River, a “ blue ribbon winding away to the sunset,” and to the east was the harbor, “ not one of its green islets missing.” West's initial notice of the absence of smokestacks, coupled with Bellamy's first (and almost his only) physical description of the city, pointed up one of the most striking facts about Boston in the year 2000. The new city was park-like, even pastoral, in character. The entire apparatus of industrialism was kept sedulously out of sight, and the landscape, both physical and social, had come to look quite pre-industrial.

    The utilization of maize silage for intensive beef production: II. The effect of urea on silage fermentation and on the voluntary intake and performance of young cattle fed maize silage-based diets (1975)
    Cambridge University Press
    Details
    Publication Date: 1975-04-01
    Description: SUMMARYMaize was cut at 22·6, 27·0 and 41·6% dry matter and ensiled in 4 kg quantities in polythene bags without additive or after the addition of urea at 0·5, 1·0, 1·5 and 2·0% of the crop dry-matter content. Silos were opened at intervals up to 96 days. Maize of 23·4% dry-matter content was ensiled in 10 t butyl rubber silos without additive or after the addition of urea at 1·0% or fishmeal at 4·0% of the crop dry-matter content.Silages from the polythene bag silos were all well preserved. pH values increased and total acid content fell with increasing maturity of the crop. Addition of urea had little effect on these values. Only with the most mature crop did ammonia content increase markedly with increasing level of urea addition. All silages from the butyl rubber silos were well preserved with low pH values and similar total acid contents.Silages from the butyl rubber silos were used to measure voluntary, intake live-weight gain and efficiency of utilization of young beef cattle. The diets fed were silage without nitrogen supplement or supplemented with urea or fishmeal, added at ensiling, at feeding or included in a concentrate feed. One third of the total dry-matter intake of all cattle was provided by a pelleted concentrate feed consisting of equal quantities of dried grass and rolled barley.The increase in nitrogen content brought about by the addition of urea or fishmeal did not affect total dry-matter or organic-matter intake but was associated with 25% increase in nitrogen consumed. Live-weight gain on all treatments with added nitrogen was 20% higher than for the unsupplemented silage. This improvement in growth rate was accompanied by significant increases in efficiency of utilization of dietary dry matter and organic matter but efficiency of nitrogen utilization was reduced. The results indicate that neither the source nor site of addition of supplementary nitrogen significantly affect live-weight gain, dry-matter intake, organic-matter intake or utilization of dry matter or organic matter. They also demonstrate that urea can be used effectively to provide supplementary nitrogen to young cattle fed a maize silage-based ration.

    A comparison of leaf and ear development in barley cultivars as affected by nitrogen supply (1978)
    Cambridge University Press
    Details
    Publication Date: 1978-06-01
    Description: SummaryTwenty-one two-row and 19 six-row barley cultivars, originating from the major barley growing areas, were compared in a duplicated experiment conducted under controlled environment conditions. Plants were grown in sand and supplied nitrate at two concentrations.Number of leaves on the mainstem and leaf emergence rate both varied widely but there were no consistent differences between two- and six-row cultivars. The low nitrogen treatment led to significant reductions in number of leaves and emergence rates. As a result of these opposing effects the time of appearance of the flag leaf was not affected by treatment. The number of leaves unfolded was a linear function of time where nitrogen was supplied at high concentration but for plants supplied with low nitrogen, appearance of the third and fourth leaves was considerably delayed. Cultivars producing fewer leaves on the mainstem also showed faster leaf emergence and both these factors contributed to the earliness of a cultivar.Low nitrogen treatments reduced number of spikelets per ear in both two-row and six-row barleys; this treatment also reduced the number of grain filled, although mean grain weight was not affected. Faster leaf emergence rates were associated with fewer spikelets per ear in both nitrogen treatments.Since they are based on a relatively large number of cultivars it is likely that these results are general for barley. The importance of further detailed examination of apical development is indicated.

    Paraformaldehyde as a silage additive (1978)
    Cambridge University Press
    Details
    Publication Date: 1978-08-01
    Description: SummaryIn three experiments, ryegrass and lucerne were ensiled for 100 days in test-tube silos containing about 100 g of crop either without additive or after the addition of paraformaldehyde or formalin to provide 0·1–0.4% of the fresh crop weight as formaldehyde (HCHO). When applied as prills containing 82% HCHO, paraformaldehyde was as effective as formalin in restricting fermentation and preventing extensive protein breakdown at comparable HCHO application rates. The lower solubility of paraformaldehyde containing 98 % HCHO as powder or prills made these forms less effective than formalin in restricting fermentation. Paraformaldehydecontaining 98% HCHO was, however, effective even at the lowest rate of application, in preventing clostridial-type fermentations when these were present in silages made from untreated crops.This was in contrast to formalin which promoted such fermentation at low rates of application.

    Acrylic acid and sodium acrylate as additives for silage (1979)
    Cambridge University Press
    Details
    Publication Date: 1979-04-01
    Description: SummaryPerennial ryegrass, lucerne and maize were ensiled for 100 days in polythene-bag silos without additive or after the addition of aorylic acid at 0·125, 0·25 and 0·50% of fresh crop weight, sodium acrylate at 0·165, 0·33 and 0·66% of fresh crop weight and formic and propionic acid at 0·25% of fresh crop weight.Both acrylic acid and sodium acrylate were effective in restricting fermentation and protein breakdown in the silo. At 0·25% acrylic acid and the corresponding rate of sodium acrylate (0·33%) they were more effective in restricting fermentation than formic or propionic acids at 0·25%. At all rates of application they were effective in preventing deterioration of maize silage exposed to air for 13 days but not with ryegrass. Lucerne silages made both with and without additives were stable when exposed to air.It is suggested that because of its non-volatility and non-corrosive properties sodium acrylate has advantages over the additives at present available.
