The annual defoliation by spruce budworm and the progressive mortality of balsam fir trees were recorded in nine study plots in northwestern Ontario over a period of 11 years. In addition to general observations on the relationship of tree mortality to defoliation, some information was obtained on the relative vulnerability of the trees with respect to size, physiological age (flowering condition), and vigor (site quality).

While scholars have provided some insight into Penny Dreadful, no one has addressed the relationship of the piece’s overall design to the writer’s vision. Indeed, Penny Dreadful is offered as a warning of a darker age to come. Accordingly, writer John Logan sets his series in a late Victorian, Gothicized London that serves as a microcosm for a contemporary Western world experiencing a psychological and spiritual disintegration that touches the individual and the larger culture. Logan calls attention to the anxieties generated by this disintegration by incorporating into his series characters from late Victorian Gothic fiction: Frankenstein and his creature, Dracula, the Wolf Man, Dorian Gray, and Dr. Jekyll. The individual and cultural anxieties suggested by these characters’ “monstrous” behaviors have their basis not only in their sexual dysfunctions but in their despair over God’s absence. This crisis is centered in sexually adventurous Vanessa Ives, whose attempts to return to the Christ Who has rejected her hold the series together. In the series’ final episode, just before her death, Vanessa has a vision of Jesus. In response to Vanessa’s death, most of the remaining characters are seized by an ennui that has its counterpart in our own culture. The suggestion is that Logan uses Vanessa Ives as a symbolic representation of a dying world view, which, somewhat ironically, provided for her remaining friends a hope that sustained them.

The efficiency of the regenerative cycle may be defined as the ratio of the heat converted into work (in British Thermal Units per pound of steam) to the heat supplied to 1 lb. of steam in the boiler plant. Where feed heating is employed, however, the heat converted into work is less than the adiabatic heat drop as calculated from the initial and final states of expansion. The difference between these quantities is termed “unavailable heat” in the paper, and the efficiency is therefore given as the ratio of the adiabatic heat drop less the unavailable heat, to the heat supplied to 1 lb. of steam in the boiler plant. The object of the paper is to illustrate the advantage derived from working in terms of unavailable heat. Values of this quantity are given, and the author provides a worked example showing their use. Appendixes I and II deal with investigations of the case in which the number of feed heating stages is infinitely great, i.e. the conditions for the ideal efficiency. The relationship of the ideal efficiency to other efficiencies corresponding to various finite numbers of feed heating stages is indicated.
