COVER

Hatching of Alligator mississippiensis.Prior to and during hatching the egg-shell becomes extensively cracked andpeels away from the underlying egg-shell membrane, The weakening andcleavage of the eggshell greatly facili-tate hatching, as the alligator has onlyto slit the eggshell membrane with theegg caruncle at the tip of it snout andthen to emerge from the egg, head first.Eggs incubated without nesting medianever hatch due to an abnormally toughshell. Length of the egg is 70 millime-ters; length of the embryo is 230 milli-meters. Hatching time (from the first tolast photograph) is 1.2 minutes. Seepage 1135. [Mark W. J.

Energy Conference: Substance and Politics.N. Conference on New and Renewable Sources of Energy held in'his past August was, from a substantive point of view, perhaps thecessful of the recent series of U.N. conferences on global issues.from the series of technical panels and crosscutting issues groupsranged from good to excellent. A synthesis report put the variousndations into a single document. The earlier drafts of the Pro-of Action had incorporated mnost of this accumulated wisdom, oftenting paragraphs supported by individual nations or by one of twooupings of nations: the Group of 77, representing the less-devel-antries and led by Venezuela, and the EC-10, or the Europeaniity, led by the United Kingdom. Delegates spent most of their timeg the various approaches represented by the alternative wording;It was a solid document providing guidelines for research andon the following energy sources: hydropower, fuel wood andbiomass, solar, geothermal, wind, oil shale and tar sands, ocean,

imal power, and peat. The delegates' attention to detail at theel meant that they were quite responsive to the recommendationssentatives of nongovernmental organizations for further clausesnergy to environment, fuel wood, or the special needs and roles of

iny in the U.N. Secretariat, however, the conference was noted a success. Previous global conferences have set up implement-:utions or funds for carrying out recommendations of the confer-iis conference did neither. The United States stood firm, andalone, against committing any new moneys to a multilateral fund,g bilateral aid and private investment. The debate on whether to setw institution was more diffuse; many delegates questioned anynit that would not include fossil fuels and nuclear power. Theme of Action essentially ducked these difficult political issues byan interim intergovernmental committee to debate the issuesnd report to the U.N. General Assembly in 1982.a deferment of the politics of the conference to the Generaly may indeed set a new model for the conferences on global issuesnizing the limits of the special meetings. Most previous conferencesmerged the substantive issues under layers of rhetoric inapplicablepic at hand and inappropriate for the powers of the conference

's the accommodating spirit of the energy conference was due to aism in the world community, one that accepts resource limitation,lerial and monetary. Credit must also go to Enrique Iglesias,(-general of the conference, who encouraged the widest possibleive debates both within the conference itself and at the parallel'ermmental Organization Forum. Many issues reflected basic devel-strategies and will require further research and evaluations. Forif priority is given to making the traditional sectors self-sufficient,t condemn these sections of a country to remain permanentghettos"? Are improved woodstoves not a way of ingraininglass existence for the poorest? What is the long-term sustainablenergy sources that will allow for the development of modernand transportation networks yet still provide a modicum of

J quality of life for the poor?riousness with which such issues were debated is a credit to the')nal community. The international donor community and nationalents should respond to this energy Programme of Action with thed technical assistance with which to carry it out.-IRENE TINKER,Equity Policy Center, 1302 Eighteenth Street, NW, Washington,36 p /"o ,
