Oh! 2.The reference to the Dublin Fusiliers getting the childer, and the reference to the Linen hall and the cannonball

I'm not sure on this one at all but I see it as conscripting the young men. The Linen Hall as the main barracks. The "one for every..." is certainly 'don't worry, Vicki, there'll be plenty of soldiers available in the Boer War (where she's gonna send yiz all) - in fact one for every cannon ball.'
