Passage: In the spring of 1868 he made his first trip to the edge of Central Asia, traveling with a Russian merchant, Vasilii Alekseich, by steamboat down the Volga to Samara, then by carriage to Orenburg, which at the time was the base for Russian military operations The Russians had occupied the Khanate of Bukhara in 1866 and were advancing toward Samarkand. In 1868, Schuyler was a guest of Tolstoi for a week at his estate at Yasnaya Polyana, at the time when Tolstoi was finishing War and Peace. He helped Tolstoi rearrange his library, and went hunting with him. Tolstoi, who was interested in public education in the United States, asked Schuyler for copies of American primers and school textbooks. Schuyler received Tolstoi's permission to translate his novel The Cossacks into English. In 1869, the new Administration of President Ulysses Grant removed Schuyler from his post in Moscow and replaced him with a political appointee. Schuyler was able to obtain a post as consul to the Russian port of Reval (now Tallinn). In November, 1869, President Grant appointed a new Minister to Russia, Andrew Curtin, a former Governor of Pennsylvania who knew nothing of Russia. Curtin was impressed by Schuyler and appointed him as the secretary of the American legation in St. Petersburg, a post which Schuyler held until 1876.

Passage: On April Fools' Day 2019, TheJournal.ie published a report on Prime Minister Theresa May's scheduled appearance on that night's special live episode of EastEnders, details of which had been leaked by Taoiseach Leo Varadkar overnight. May's purpose was to issue a final plea for unity as Brexit entered a critical stage. The internet publication featured a photograph of May in The Queen Victoria pub, with the caption "Rehearsal shot of hostile locals witnessing May's arrival". It even went so far as to compose fake documents to back up its claim, including a draft script said to have been provided by the BBC to highlight the ever-changing difficulties of keeping up with political events as they rapidly unfolded: "'This is the 416th draft' the source said. 'And her appearance was only confirmed at the start of March. Brexit won't stop f*****g, c*****g changing every two seconds. It's driving the actors mad.'" A short video clip shows actor Adam Woodyatt (who portrays the character of Ian Beale) being comforted by colleague Steve McFadden (who portrays the character Phil Mitchell), as Woodyatt bursts into tears due to the protracted rehearsals. The preliminary script — which, TheJournal.ie reminded readers, was "contingent on what the hell happens in Brexit over the course of today" — had Dot Cotton (played by June Brown) gasping as Theresa May enters the pub. May, having begun her speech, is interrupted by Mick Carter (played by Danny Dyer) who knocks over a pint and a chair in his efforts to have the Prime Minister leave the pub. May departs and perches herself despondently on a park bench, whereupon Kat Slater (played by Jessie Wallace) approaches her with "Alright love? What's getting you down?" May tells Slater she has already blamed everyone — the Irish, the Democratic Unionist Party, the European Union — and is at a loss for who is left for her to find fault with now. Slater advises her to be honest. May finds solace in this, thanks Slater, remarks on the chilliness of the night and Slater hands the Prime Minister her leopard print jacket to put on. May returns to the pub and seemingly converts all the customers bar Dot Cotton, who is promptly ejected onto the street.
