I spent three terms in Toronto, studying under McCool's guidance. Most of my resesarch time was devoted to the Kervaire-Laudenbach Conjecture. Howie's ``locally indicable'' paper [H] was the inspiration. I was trying hard to prove the conjecture for locally non-perfect groups; that happenned to be too difficult, not just for me, but for the others working in the area at the time as well. I gave up, like everybody else, and published the article , which contains an algebraic version of Howie's proof, and also a stronger result using the p-adic completions of free groups. Similar results were proved by Gersten [G] and Stallings [S].
