The poems in this book are selected from a lifetime of 'poetical prosing'. They have been placed in an order which suggests the changes from childhood to old age. Before putting it into the hands of your nearest and dearest, you'd better read them yourself.

Slugs and snails are part of the great Phylum Mollusca, a group that contains creatures as varied as the fast-moving squid or the sedentary clams, cockles and mussels. The largest group, however, are the gastropods, animals originally with a single foot and a single coiled shell.

This monograph on pest slugs and snails reviews the problems they create as plant pests in horticulture, agriculture, and forestry, and also as intermediate hosts for parasitic trematodes, cestodes and nematodes which cause worm diseases in man and domestic animals. Here only those vector snails which inhabit flooded or constantly irrigated fields, water storage reservoirs or farm ponds are considered. Reference is also made to the role of pulmonates as carriers of the agents of disease - viruses, bacteria, fungi and worms' eggs, which may be transmitted to man with inadequately cleaned vegetables and fruit. The use of molluscs as indicators of chemical pollution of soil and water, methods of mass rearing of experimental animals and also marking methods are all discussed, as are threshold limit, critical number and the prognosis of damage in plant protection. A classification, an identification key and a systematic check-list of both pest slugs and snails and their predators are provided. The book reviews the biology, physiology, metabolism, reproduction and dispersal of freshwater and terrestrial gastropods, and also the ecological factors which allow a population explosion to occur, thus increasing the likelihood of damage to crops, or the spread of worm diseases of man and domestic animals. The interaction of parasitic worm larvae and their snail hosts is also discussed. These aspects all form an essential basis for the resolution of problems of control.
