Canals and Their Architecture by Robert Harris

Harris, Robert. Canals and Their Architecture. New York: Frederick A. Praeger, 1969.

Water has always been an important part of human life. Drinking water is a necessity, but that is only the beginning of our uses of it. Water is also an element in agriculture, industry, transportation and commerce.

It is water’s role in transportation and commerce that Robert Harris focused on in Canals and Their Architecture. At times, artificial or modified waterways have been major means of transporting products in bulk.

Harris mentions canals from continental Europe and North America, especially the United States, but his book is mainly about the canals of Britain. This is an appropriate focus because the canal boom in Britain both fed and was fed by the Industrial Revolution that started there.

The boom began with the Duke of Bridgewater’s famous canal, construction of which began in 1760. The duke owned coalmines and wanted a cheaper way get coal to the mills and factories in Manchester. The canal was by no means an easy or inexpensive project, but it was greatly successful and the wealth put into it was regains many times over.

Bridgewater recognized the talents of millwright James Brindley, who went on to become the most prominent canal engineer of his day. Harris discussed the works of several British engineers who were successors of Brindley including Thomas Telford, John Rennie, and William Edwards.

As the title of the book suggests, it is organized mainly by the types of structures found on canals. In addition to the canal cut, Harris wrote about bridges and auqueducts, locks , tunnels, boats, buildings and unique ways of handling elevation changes on a canal route. Early canals followed the contours of the land to avoid the use of expensive and complex equipment and, where needed, were crossed by utilitarian bridges of wood or brick. As canals became straighter, and more lucrative, they added locks and other mechanisms for raising and lowering boats. The materials became more varied and complex, including stone and iron. Spectacular aqueducts carried canals over low lands. Tunnels were well-made features of canals early on because the technology for building them was readily adapted from mining.

The older canals are impressive in that so much was done with manpower and simple tools. As canals aided other industries, the improvements those industries spawned, especially in iron construction and railroads, returned to canals and the way they were made. The construction of modern canals is the work of enormous equipment.



Canals and Their Architecture includes many illustrations and photographs. These are very helpful for the laymen to see the types of structures discussed in the text, though even an engineer familiar with the terms will likely appreciate the images.

The Revenge of Analog by David Sax

The joke about visions of the future that never panned out is usually, “Where is my flying car?” The proliferation and promises of digital technology over the last two or three decade might prompt us to pose some other questions such as, “Where is my paperless office?”

In The Revenge of Analog, journalist David Sax discusses how analog technologies are sometimes thriving in the digital ages. Some are making comebacks. Some never went away. Some are growing more popular because of digital technology, not in spite of it.

Sax looks at a lot of analog technologies. This includes vinyl records, paper and pen, tabletop games, books and brick-and-mortar stores.

Some of these have very interesting histories in how they have fallen, risen and interacted with digital technology. What I found most interesting in the book is the reasons analog persists. It is usually because it brings something that digital technology leaves out.

For instance, analog technology appeals to the senses. I know a lot of bibliophiles who love the smell of books, though it would not seem to be a pertinent feature. The IRL space is simply much richer that even the most detailed virtual space.

 “There’s never going to be a virtual environment as completely engaging as the physical environment is,” computer game designer Bernie De Koven quoted in The Revenge of Analog

Analog is usually slow. Generally, a strength of digital is that it is almost always faster. We don’t always want fast. Sometime the slower pace, the pauses, helps us to take things in and savor them. For instance, when you listen to a vinyl record, you can’t skip songs at the touch of a button, you have to lift the needle and move it or even change records. You can’t listen to any songs you have in random order, but you have to listen to song on a single album in the order the artist or producer arranged them unless you introduce a lot of pauses as you interact with the discs and player.

Analog is limited. The digital world can be so rich with information and choices that it can be overwhelming. Paper and pen limits the size, colors and effects you can produce. These limitations help us hone in on the main issues quickly and get moving.

“People think limitations are bad things. But it moves the process forward, in a good way. You can easily get lost in the process. It’s easier to stick to a plan when you have limitations,” analog recording studio owner Chris Mara quoted in The Revenge of Analog

In the real realm of communication, analog is more intimate that digital. The ultimate analog communication is a face-to-face conversation, mediated by nothing but the air in between two people. We send off a lot of nonverbal signals when we speak, and we sense these signals from others, which gives us a more rich and nuanced understanding of what is said (and unsaid) than we can get from a text message or even over Skype or Facetime.

London Under by Peter Ackroyd

London is an ancient city. The Romans established a settlement their a thousand years ago, but they weren’t the first inhabitants of the valley. It sits on soil into which everything slowly sinks. Rivers that brought life to the valley became choked with filth and were buried. The ground under London is thick with history, and the infrastructure of a modern metropolis mingles with the remains of its ancestors. Peter Ackroyd describes what is beneath the surface of that great city in London Under.

Ackroyd goes back to the earliest settlers of the area and the archeological remains of their lives. Their holy places were overbuilt by Roman temples. The temples dedicated to Roman gods were overbuilt by churches. Old paths became Roman roads. The filth of a city covered these roads and turned them back into dirt paths. Modern people paved them anew with brick, and later asphalt or concrete. It’s all still there, though, one thing layered over the other, but often still following the outlines ancient paths.

As you might expect from a man with who has worked with water, some of my favorite chapters relate to the rivers and sewers. London was built around rivers. As the population grew, these rivers became open sewers, carrying away all manner of waste until they were too filthy and stinking to bear. These rivers were enclosed and became underground sewers. As the city grew, it overwhelmed the sewers and turned the Thames into a stinking mess. Eventually it inconvenienced Parliament enough that they engaged the problems seriously in the 19^th Century, putting in place interceptor sewers that carried the waste away from the city. Many of the sewers that are now more than a century old are still in use.

Another feature of London that fascinates my engineering side is the Underground. The city has the oldest underground railway system. The first lines are more than 150 years old. It was built in bits and pieces by competing private companies, though now it is a unified system. The Underground has become such a part of London life that a literature related to it has developed. The tunnels have been the settings of novels and the inspiration for poems.

World War II and the Cold War were another significant phase of buried construction. The British government built many tunnels and bunkers to protect government resources threatened by war. During World War II, so many people sought shelter in the Underground that the government was forced to provide shelter space for people escaping the bombs.

Like any modern city, London now has an extensive underground infrastructure. Pipelines carry drinking water, sewerage, electric and telephone wires, fiber optic cables and all the other things that connect people to services in their homes and workplaces.  These important systems are hidden underground, out of site and possibly too often out of mind, where their work apparently does not disturb the sleeping remains of the many things that had come before.
