Building Ardnacrusha

I had a page with photos of the construction of Ardnacrusha in 1930; I have expanded that page to include

  • photos taken in the 1920s by Eyre Chatterton and kindly supplied by Tony and Blair Chatterton
  • links to the ESB Archive’s reports made by Siemens during construction; h/t Carthach O’Maonaigh for drawing them to my attention.

 

Grand Canal: early plans

This page has a map of the planned route of the Grand Canal from Dublin to the Shannon via the Brosna, with branches to the Barrow and the Boyne, as proposed in 1779.

Note that I know nothing about the site displaying the map and I do not know whether it might endanger your computer’s security in any way. Mine seems to be OK [so far] [touch wood].

First steamer across the Atlantic: new evidence

According to the Irish Times of 11 February 2017

Margaret Gaffney was born on Christmas Day 1813, in Tully, Co Leitrim. Five years later, faced with extreme poverty and religious persecution, her parents and the three youngest of their six children, including Margaret, boarded a steamer bound for Boston.

Eoin Butler, the author of the article, provides no details of the vessel, but I hope he will: up to now folk have believed that an American vessel called the Savannah was the first to use steam on any part of the Atlantic crossing, and that was in 1819, the year after Margaret Gaffney’s crossing.

 

Another waterways mystery

According to Ruth Delany [Ruth Delany and Ian Bath Ireland’s Royal Canal 1789–2009 The Lilliput Press, Dublin 2010], the Royal Canal’s fast passenger-carrying fly-boats had neither toilets nor cooking facilities; the slower night-boats were better equipped.

So how did the fly-boat passengers relieve themselves?

Given that the boats travelled at six Irish miles per hour (about 12 km/h), any passenger who disembarked for the purpose would have found it difficult to catch up again. Yet standing on the notoriously unstable boats might have been difficult for the gentlemen, while the problems facing the ladies are not to be contemplated.

I don’t think that the india-rubber urinal had been invented by then. So what did they do?

 

Tories on the Barrow and the Shannon

I read here that Olivia O’Leary, who chairs a Save the Barrow Line committee, says that the Barrow Line (trackway or towing-path)

[…] is a natural amenity and should be maintained as it is.

It isn’t. It is an entirely artificial creation, built to enable the use of horses to tow boats. Any geraniums, beetles, butterflies or tweetie-birds using it are interlopers, squatters and trespassers and should be paying rent; at the very least they should take second place to humans.

The Grand Canal Company often complained about the poor quality of the Barrow trackway: the surface was not up to the job. If it is to cater for more users, it may well need to be improved. That is an engineering decision on which I am not competent to pronounce but, as the Barrow is pretty well a dead loss for long-distance cruising by larger boats, it needs to be redesigned for walkers, cyclists and canoeists.

But at least the Barrow NIMBYs are prepared to accept more boats. Dr William O’Connor of the Old River Shannon Research Group writes about the Shannon here, complaining about the small number of “garish canoes” that occasionally travel downstream from Castleconnell to Clareville. Dr O’Connor asks

[…] why has it become a free-for-all for canoeists?

The answer is that there is a right to navigate, as I pointed out here (with an addendum here): I have had no response from the ESB so, while being open to correction, I maintain my position. Anglers may believe that their interests are paramount on that stretch of the Shannon: I disagree. Of course I would be all in favour of discussions between anglers, kayakers, dog-walkers and other users (even environmentalists), but such discussions cannot be based on a presumption that one group has all the rights, or that one activity is of supreme importance, and that the rest are secondary.

For some reason, canoes operated by commercial providers are particularly to be condemned, although it is not clear how salmon and lampreys can distinguish between public-sector, private-sector and voluntary-sector canoes — or whether they would be bothered anyway: Dr William O’Connor says

It is noted that there has been little scientific research on the ecological impact of canoeing.

In other words, there is no reason to believe that there is any basis for the concerns expressed by Dr O’Connor or by various anglers. Of course if anyone did want to commission such research, it could be provided by the Ecofact consultancy in Limerick, whose principal is a Dr William O’Connor.

More broadly, though, the common factor on the Shannon and the Barrow is that existing users of public facilities are resisting new or expanded uses and seeking to protect their privileges. Irish Toryism is alive and well.

Addendum: this is probably the solution to the salmon problem.

Boarding in Limerick

On the morning of the day on which I left Limerick, a truly melancholy and fatal accident occurred. Just as the steamer which starts every morning for Kilrush and Kilkee, was in the act of leaving the quay, a car was seen to approach very rapidly to the station, from which the vessel had just begun to move. Planks are not used at these quays, the water being sufficiently deep to admit of the steamer lying so close as to enable the passengers to step off from the quay on board the vessel.

A fine young man jumped off the car, and took a female who was on the opposite side in his arms, and ran with her to the packet, and had just succeeded in placing her feet in the side of the boat. In order to get her safely aboard he had to push her forward, and by this means accomplished the object he had in view. But alas! in achieving so much for her, he lost himself; for at this moment the packet moved off, and it became impossible for him to reach her; while the efforts he had previously made to get the lady on board occasioned him to stretch so far forward that it was equally impossible for him to recover his upright position on the quay. The consequence was that he fell between the quay and the steamer, and, as it was supposed, was struck by a revolution of the paddle, for he never rose.

What must have been the feelings of the poor female in witnessing the sudden and melancholy death of her gallant preserver? She was in delicate health, and was about to proceed to Kilkee for the benefit of sea-bathing, when this awfully heartrending event took place, which deprived her of him who was her darling and her pride; for alas! he was her son.

Seasteading

Update here from Alex Tabarrok.

Presumably the USA will be sending guided-missile destroyers to deter occupation.

Lough Neagh sand trade

The sand trade on Lough Neagh

The sand trade on Lough Neagh

Paul Whittle has spent much time researching and writing a history of the UK marine aggregate dredging industry. He is now publishing it online in blog format. It includes a chapter on the Lough Neagh sand trade, which is the most comprehensive account I’ve seen and well worth a read.

The Air-Balloon

Having justly excited the public attention of Europe, as a phaenomenon the most wonderful, and likely to reach the summit of perfection and general utility, Mr RIDDICK, pupil to Mr DINWIDDIE, and lately with him at the construction of those exhibited in London, will, on Monday and Tuesday next, between one and three, at the Rotunda, float an AIR-BALLOON, upwards of Six Feet diameter.

Admittance 2s 2d — when a Ticket will also be delivered gratis, for admission to the Gardens, the day it shall be LAUNCHED, notice of which will be given in this paper.
