Leslie Jackman’s Marine Aquaria

 



Leslie Jackman was a man of many parts: teacher, broadcaster, museum officer, film-maker, and author [1]. He was a noted natural historian and an important influence on a generation of young people, of which I was one, and I had the added bonus of meeting him, as we both lived in Paignton in Torbay [2]. Although he wrote about terrestrial natural history and the life found in streams, rivers and lakes, Leslie seemed especially fascinated by the coast and by marine biology. He encouraged others to share his enthusiasm by “rock-pooling” and by looking at plants and animals in aquaria.

This is clear in the Preface of Marine Aquaria [3]:



The address given in the Preface is “The Seashore Aquarium, Paignton” and this was run by Leslie and, if my memory serves me correctly, was located adjacent to Paignton Harbour in the building shown in the image at the top of this blog post. This was a fitting site, as many specimens were brought to the aquarium by local fisherman [3].  

It is clear that Leslie pays homage to Gosse and later in the book we read:

The first great seashore observer was Gosse. He lived a hundred years ago, but his writings are classics of observational work. Gosse never lost the freshness of excitement that came from new discovery and his appetite for knowledge was insatiable. If you desire, as did Gosse’s friend Charles Kingsley in Glaucus, to walk on and in under the waves” you will have found a new and absorbing interest in your aquarium.

Gosse’s The Aquarium [4] and the handbook based on the final chapter of the earlier book and sold at a price that made it more available to a wide audience [5] contain all the information needed for aspiring aquarists.

Marine Aquaria, written more than 60 years ago, had much in common with the earlier works by Gosse and they cover the same ground. Of course, there are differences in that Leslie discusses the use of plastics and air pumps, neither being available in Gosse’s day. Intriguingly, we read in Marine Aquaria that good conditions for animals can be provided by an aeration system based on reservoirs (see below, upper) and this is almost identical to a system that Gosse rigged up in his home in Torquay [2]. Gosse’s observation tank was, however, less elaborate than that shown in The Aquarium, this being a top-of-the-range parlour model with all the plumbing hidden in the pedestal (see below, lower).



So, what was the audience for the books by Henry Gosse and Leslie Jackman? Judging by the Preface of Marine Aquaria, the audience was male, but this was, of course, just a form of expression of the times and Leslie promoted an interest in natural history in boys, girls, men and women. Interestingly, women played an important part in the development of collecting on the shore - Anna Atkins with her cyanotypes of algae [6], Anne Pratt with her seashore guide [7], and Margaret Gatty with her work on seaweeds [8]. Torbay, and the adjacent coastline, was something of a mecca for the popular appreciation of life on the shore for both men and women, the latter having to pay special attention to the clothes that they wore [9]. In addition to Gosse, Amelia Griffiths was resident in the town, making important contributions to the study of algae [8], and, as Leslie Jackman mentions, Charles Kingsley also visited Torbay in the 1850s and in Glaucus heaps praise on Henry Gosse. The two became close friends [2].

What has happened to our interest in life on the shore and in marine biology since the publication of Leslie Jackman’s book? There was clearly little difference between its content, and advice, to that which had been published a hundred years before. Many of us still enjoy looking in rock pools and there are many aquarists, although few collect animals from the shore for their aquaria. We can SCUBA dive, or snorkel, if we want to see marine organisms in their natural environment, and we can visit huge aquaria that are now part of the entertainment industry, with tanks so large that they approximate to natural habitat (although the animals and plants that they contain are selected by the aquarium managers). Both have an educational value, but there is no longer an appetite for making one’s own aquarium to allow close observation. We now have numerous videoclips for that and there are also wonderfully-shot TV programmes that we can enjoy in the comfort of our living rooms, but how real is it to us? 

Something is missing from the thrill that Henry Gosse and Leslie Jackman encouraged – something that is life-enhancing, as any first-hand study of the natural world will be. I collected plants and animals and had aquarium tanks at school [2] and even kept some animals in bowls at home. I am very grateful that I knew Leslie Jackman – and I feel that I know Henry Gosse – and I am also grateful to have been brought up in Torbay and collected on the shores that inspired them. They inspired me, too.
