Naturally, in a group of animals as diverse as the snakes, and with so many varied enemies, there are numerous defensive reactions and devices. There is, however, one general pattern of behavior. In the presence of suspected enemy the first reaction is to try to escape observation; if this fails, the next resort is the flight to some inaccessible retreat, but if this is not possible, or is circumvented, various kinds of intimidatory gestures and warning devices are brought into play; in the last resort the snake attacks. This pattern varies with the circumstances; some stages may be omitted or combined unpredictably whilst; some notoriously irascible species may dispense with all the preliminaries and attack almost at once, though seldom or never without some provocation. Amongst the factors that increase aggressiveness are hunger, the mating season and surprise, with the last mentioned the commonest; when hunting for food or for mate, activity and the aggressive instinct are both at their peak. Owing to their poor sense of hearing snakes are very liable to be, quite literally, caught napping and a similar situation arises during their periods of temporary blindness just before sloughing (蜕皮) begins. By far the greatest number of snake-bit accidents result from the unwitting disturbance of resting snakes, and this hazard is much increased with species that are well disguised and whose natural instinct is to trust to this concealment as their principal defense. As well as differences in aggressiveness between individuals of the same species according to the circumstances and conditions, there are also notable differences between species, even closely allied species; and the reports of those who have been attacked may understandably be lacking in objectivity. So it is impossible to forecast, even in outline, how any encounter will develop. The Hamadryad, for example, is usually credited with being amongst the most aggressive of snakes, and there are many accounts of unprovoked attacks, yet on one occasion fourteen men and seven dogs passed and returned within two yards from a nest and no snake was seen although the female, which guards the nest, could not have been far away. A snake is most aggressive when

Roger Rosenblatt’s book Black Fiction, in attempting to apply literary rather than sociopolitical criteria to its subject, successfully alters the approach taken by most previous studies. As Rosenblatt notes, criticism of Black writing has often served as an excuse for expounding on Black history. Addison Gayle’s recent work, for example, judges the value of Black fiction by overtly political standards, faring each work according to the notions of Black identity which it put forward. Although fiction assuredly springs from political circumstances, its authors react to those circumstances in ways other than ideological, and talking about novels and stories primarily as instruments of ideology limits much of the fictional enterprise. Rosenblatt’s literary analysis discloses relations and connotations among works of Black fiction which solely political studies have overlooked or ignored. Writing acceptable criticism of Black fiction, however, presupposes giving satisfactory answers to a number of questions. First of all, is there a sufficient reason, other than the racial identity of the authors, to group together works by Black authors Second, how does Black fiction make itself distinct from other modem fiction with which it is largely contemporaneous Rosenblatt’s idea shows that Black fiction constitutes a distinct body of writing that has an identifiable, coherent literary tradition. Looking at novels written by Blacks over the last eighty years, he discovers recurring concerns and designs independent of chronology. These structures are thematic, and they spring, not surprisingly, from the central fact that the Black characters in these novels exist in a predominantly White culture, whether they try to conform to that culture or rebel against it. Black Fiction does leave some aesthetic questions open. Rosenblatt’s thematic analysis permits considerable objectivity; he even states that it is not his intention to judge the merit of the various works--yet his reluctance seems misplaced, especially since an attempt to appraise might have led to interesting results. For instance, some of the novels appear to be structurally diffused. Is this a defect, or are the authors working out of, or trying to create, a different kind of aesthetic In addition, the style of some Black novels, like Jean Toomer’s Cane, verges on expressionism or surrealism; does this technique provide a counterpoint to the popular theme that describes the fate against which Black heroes are struggling, a theme usually conveyed by more naturalistic modes of expression In spite of such omissions, what Rosenblatt does include in his discussion makes for a keen and worthwhile study. Black Fiction surveys a wide variety of novels, bringing to our attention in the process some fascinating and little-known works like James Weldon Johnson’s Autobiography of an Ex-Colored Man. Its argument is tightly constructed, and its forthright, clear style exemplifies levelheaded and penetrating criticism. Roger Rosenblatt looked at Addison Gayle’s criticism of Black Fiction with a(n) ______ attitude.
