According to
Thom's, "Michael Meade
& Son," 153-59 Great Brunswick Street, were building
contractors with "sawing, planing, and moulding mills"
facilities. The sawmill business owned by "
Alderman Meade" is also
mentioned in the 28 March 1906 annual special issue of
Timber
and Wood Working Machinery, published in London. Glossing
the "
piled balks," Slote quotes the definition in the
OED: "A roughly squared beam of timber, sometimes used
technically to designate Baltic timber, which is roughly dressed
before shipment."
Why mention this business, twice? Senan Molony's
The Phoenix
Park Murders (Mercier, 2006) observes that it employed
James Carey as a bricklayer for eighteen years. Carey lived not
far from the lumber yard on
Denzille
Street (renamed Fenian Street after independence). He was
a central figure of the Invincibles, the
Fenian militants who assassinated
two top government administrators in front of the Viceregal
Lodge in Phoenix Park on 6 May 1882. Before leaving Dublin for a
new life after the trials for the murders, which he had planned
and was centrally involved in before turning State’s evidence
against his co-conspirators, Carey transferred most of his
property portfolio to Michael Meade, his former employer. This
caused a sensation when it became known in Dublin in 1883. Carey
left behind a legal row over his alleged "fraudulent deed" of
transfer and a demand that the houses be sold to raise the money
towards his civic debts. Meade eventually kept his new
properties.
The words before and after the mention of Meade's business in
Hades might be taken as insinuating his involvement in
Fenian politics. A “National school" called St. Andrew's was sited
on Great Brunswick Street. Referring to it as Bloom does,
however, may suggest that Meade’s was a school of Nationalism.
“The hazard” is a cabstand,
nothing necessarily hazardous about it. However, the
Invincibles were transported to and from the site of the
murders by cabs, several of them were cabbies, and Dubliners
in the novel think that the operator of the cabman's shelter
in Eumaeus is James Fitzharris, a.k.a. "Skin the
Goat," the cabbie who drove a decoy cab from Phoenix Park to
central Dublin to confuse the authorities. There was certainly
a hazard in Fenian nationalism, and not only for government
authorities: a participant risked his life if caught or
betrayed.
