As of May 1916, the Imperial Aircraft Flotilla consisted of 91 machines purchased with funds donated by Britons overseas, 69 for the RFC and 22 for the RNAS. The RFC donations were organised through the Over-Seas Club -- £1500 for a B.E.2c and £2250 for a Vickers F.B.5 -- and were as follows.1

Since I'll be undertaking a research trip to the UK this November or so, I need to think about exactly what I'm going to do there. Giving a paper at the AHA is part of that process. That will hopefully help me formulate my approach or at least identify potential approaches to comparing airship, spy and invasion scares in the First World War. But I also need to nail down where I am going to go in a very physical and literal sense. This is because I want to get out of London for at least a week, to look at scares in a provincial area, and raid the local archives for civil defence files or personal diaries and so on (which of course I can supplement in the London archives). This is partly because it'd be nice to avoid the London-centric perspective for change, but also because I suspect that such fears could be as or even more intense in outlying areas -- particularly on the eastern coast facing Germany. I had been thinking somewhere like Hull, which was raided by Zeppelins on multiple occasions, or East Anglia which is the closest part to Germany and so an obvious (at least in the folk sense) place for a German invasion or raid. Both areas also had notable phantom airship sightings in 1913. So maybe there. Or maybe somewhere else.

I wondered if it there was perhaps a systematic way of gauging fears along the invasion coast, something better than throwing darts at a map. And it occurred to me that I might be able to use the British Newspaper Archive (BNA) for this. We're all used to n-grams by now, which are great for tracking the varying usage of words over time. Tim Sherratt's QueryPic does this for Australian newspapers based on the Trove Newspapers corpus; though there's nothing similar for BNA that I know of, you can manually extract the data yourself without it getting too tedious. What I am thinking of might be termed an n-map: an n-gram across space instead of across time. It's a very obvious thing to do, but I don't think I've seen it done for the databases I'm used to using. It's really just GIS (without an actual map). Or distant (newspaper and map) reading.

There's no publicly-available BNA API to make it possible to do this in an automatic way, but again it is actually not too difficult to use the BNA interface manually. This is because BNA has a very fine level of geographic discrimination: all newspapers in the database are allocated a place (e.g. Hull), a county (e.g. East Riding of Yorkshire) and a region (e.g. Yorkshire and the Humber). These appear as filters when you do a search, and listed beside each filter is the number of issues the search has thrown up for it. So you can just copy down the numbers into a spreadsheet to construct your own low-tech n-map (or n-gram, for that matter).

So now the question is, what keywords do I use? This is not completely straightforward, though neither does it have to be airtight. This is just back-of-the-envelope stuff, after all. After some experimentation, I ended up going with 'zeppelin'; 'invasion'; and 'spy'. (BNA automatically searches on plurals as well.) Here are the number of articles in the BNA for each keyword for each region, for the period 4 August 1914 to 11 November 1918.

Ottawa Evening Journal, 15 February 1915, 1

On 15 February 1915, the Winnipeg Evening Tribune's daily astrology column noted the unfavourable positions of Mars and Uranus:

The affliction of Mars this month is ominous of outrages against persons in power. A disaster that will shock the people living in cities is threatened.

Uranus foreshadows peril from aeroplanes or Zeppelins. National alarm from unexpected causes is presaged by the planets.1

Readers might indeed have been excused for being alarmed, for the previous evening, Ottawa, the Canadian capital, had been placed on high alert due to reports of aircraft approaching it from the United States border. While no attack actually eventuated, the omens were not good -- at least according to the McClure Newspaper Syndicate's anonymous astrologer.

Press interest in airships, January-April 1913

'Everybody's Doing It' was the name of a popular revue which opened in the West End in February 1912; the music and lyrics (including a near-eponymous song) were co-written by Irving Berlin. It was also the Manchester Guardian's stab at a contemporary pop cultural reference to describe just how widespread the phantom airship scare had become by the start of March 1913. There are more concrete ways to express this than ragtime. Geography is one; chronology is another.

The graph above shows two things. (After relying on Plot for many years, I've switched to DataGraph, which is not free but is more powerful and much easier to use.) The blue bars represent the number of British periodicals (mostly daily newspapers, London and provincial) which mentioned mystery airships on each day in January-April 1913, while the red bars represent the number which mentioned airships, whether mysterious or non-mysterious (for example, the activities of German or British military dirigibles). It doesn't matter whether a newspaper mentioned scareships once as a humorous aside or devoted half a page to a topic, both are counted equally here. Three phases can immediately be distinguished. (I must admit to having fudged the data a little bit: I've assumed that every issue of the Aeroplane would have mentioned airships, as I don't have access to copies to check. Flight certainly did.) The first, from the start of January through the third week of February, is characterised by a relatively low level of press interest in airships, in which references to mystery airships predominate (though not so much towards the end of this period). The second phase is clearly the peak of the phantom airship scare, the last week of February and the first week of March, when more than two or three times the usual number of periodicals talked about airships, overwhelmingly the mysterious kind. The third phase extends from the second week of March until the end of April. There are far fewer mentions of scareships here, even compared to the first phase. But interestingly, the amount of attention paid to airships in general remains very high: several times that of the first period, and not too far short of that in the second, peak period.

Western horizon from London, 21 February 1913, 8.30pm

The planet Venus normally sticks close to the Sun and so can only be seen very shortly after sunset, to the west (or before sunrise, to the east, when it is a morning star). But every 584 days, when it reaches maximum elongation in its orbit, it is far enough from the Sun in apparent terms that it remains visible for quite some time after dusk. It also relatively close to the Earth at this time and so unusually bright: only the Moon is brighter. At such times Venus dominates the western sky and it can be very startling, especially for the infrequent stargazer.

As it happens, Venus reached maximum elongation on 11 February 1913, right in the middle of the phantom airship scare. The above thumbnail probably isn't very clear, but the full-size version, made with Stellarium, shows the western horizon from London at 8.30pm on 21 February 1913, the beginning of the scare's peak. (London without any buildings, light pollution or clouds, admittedly, but the view would have been roughly the same from anywhere in the British Isles.) Venus can be seen low above the horizon, almost exactly due west, and extremely bright (apparent magnitude -4.1, though extincted by the atmosphere to -3.2). Anyone who happened to glance in that direction would see a brilliant light hovering in the distance, very different to the other stars and even planets. If they watched it for a few minutes they might see it drifting northwards and perhaps sinking lower; if there were clouds scudding by or trees waving in the wind the effect might be enhanced. It would be very easy to think an aircraft was flying about, equipped with a searchlight.

Daily Mirror, 17 February 1913, 5

The Daily Mirror has a curious item today under the headline 'BRITAIN'S PERIL IN THE AIR' (p. 5; above). It is apparently a statement made yesterday by an unidentified 'famous naval tactician', but instead of setting it out as an article or a letter to the editor it is given as an extended quotation with no gloss apart from the hint about the person's identity. Even if it is from an interview, it's an unusual way of doing things.

Uses of 'Mars' and 'canals' vs uses of 'Mars' only in peer-reviewed astronomical articles, 1861-1970

So, to wrap up this accidental series. To check whether professional astronomical journals displayed the same patterns in discussing 'Mars' and 'canals' as the more popular/amateur ones I again looked at the peak decade 1891-1900, this time selecting only the more serious, respected journals. However, because of the French problem I had to exclude L'Astronomie and Ciel et Terre (the former was apparently more popular anyway). So for my top three I ended up with Astronomische Nachrichten, Publications of the Astronomical Society of the Pacific (PASP) and Monthly Notices of the Royal Astronomical Society (MNRAS). Astronomische Nachrichten ('astronomical notes') was the leading astronomical journal of the 19th century, founded 1821. It published articles in a number of languages including English. Fulltext Service seems to be multilingual, as it picks up the German (at least) equivalents of Mars/Martian and canal/canals. That doesn't help with the French problem, but that will only affect a small minority of Astronomische Nachrichten's articles. The Astronomical Society of the Pacific was founded in California as a joint amateur-professional organisation. Its PASP is now a very highly regarded journal, although I must admit I don't know if this was always the case. MNRAS is the journal of the Royal Astronomical Society in Britain. It also happens to be where my solitary peer-reviewed astronomy article was published (and when I say 'my', I think approximately 1 sentence relates to research I actually undertook), but even so it really is a highly-respected journal.

In my post about the lingering scientific interest in the Martian canals hypothesis after 1909, I said that there was a problem with journal coverage. What do I mean by this? Have a look:

Uses of 'Mars' and 'canals' in peer-reviewed astronomical articles

This is a repeat of the first plot in the previous post, showing the number of articles published in peer-reviewed astronomical journals mentioning 'Mars' and 'canals' between 1861 and 1970, only this time for each of three journals: Observatory, Journal of the British Astronomical Association, and Popular Astronomy. I chose these three because they were the journals which had the most such articles, both over the entire period and in the peak decade of the 1890s.

Uses of 'Mars' and 'canals' in peer-reviewed astronomical articles

In a recent, hmm, let's call it a discussion resulting from an old post I wrote about the US Air Force's one-time interesting in mapping Mars, I tried to assess how scientific interest in the Martian canals hypothesis lingered after the early 20th century, and said I would run up some figures to illustrate the data. So here they are.

My source is the ADSLabs Fulltext Service. ADS is the Astrophysical Data System, an online database of articles published in astronomy and physics journals. Which doesn't sound so amazing these days, but it was in 1994 when I first used it! (More on its history here.) The interface has changed remarkably little since then, but it is still free and very comprehensive. While it is primarily an abstract service, fulltext is available for many older articles -- but only as non-searchable images. Moreover, not all articles have abstracts. However, the text of articles from most of the major journals have been OCRed into a parallel database, the Fulltext Service. Like the classic ADS Abstract Service, this was not designed with historians in mind, but it's still quite useful.

In my discussion of the ill-fated Sykes Memo, I noted that it included proposed force levels for the Dominion air forces, which I haven't seen discussed before. This is interesting because it came at an interesting moment. It's early December 1918, with the Empire was in the flush of victory and all things seeming possible (at least they did to Sykes, which is why he lost his job as Chief of the Air Staff). But it's before any of the Dominions had actually created their own independent air forces (SAAF: 1920; RAAF: 1921; RCAF: 1924; RNZAF: 1937 -- though those dates are inevitably contentious; see Pathfinder 114 for a RAAF perspective). Their decisions to do so inevitably reflected local concerns and conditions, but they also took advice from the RAF, as the Empire's 'mother' air force. So Sykes's proposals provides some insight into how the centre viewed the periphery in an airpower sense at this cusp between war and peace, and what advice he might have given the fledging air forces had he not been ejected from command of the RAF.

So, as before, I've tabulated the squadron numbers from the Sykes Memo in From Many Angles, and added some comments after.1
