The Times 29088

[TioMateo]

Thanks to all for previous answers, but I'm still struggling :-

1)Is a tusk regularly filled with strange bulges at the front? (8) S?L?E?T?

2)  Remark's caught you shouldn't have to write down (6)     N?T?T?  Why is it NOTATE?

3)Taking up arms --  Gun before it recoils in long shot (9)        R?V?L?I?G.  Why is it REVOLTING?

1 Salients - 'iA a TuSk' (regularly) filled with 'alien' (strange)
2 Notate - 'note' (remark, caught; contains) 'ta' (you shouldn't have)
3 Revolting - 'rev' (gun; an engine, eg) + 'it' (back, in) anag 'long'
