Today's Telegraph cryptic

[pldcav]

These are for my mother, not me, so I may not have the wording exactly right.  One seems to be TARMAC, but we can't see why:

Black stuff Sally found on the bone (6) t-r-a-

and the other we suspect ends ERI:

Be busily active, hesitantly with one of the bones (6) -n-e-i

Any assistance or correction to the clue wording would be most welcome!

Black Stuff  Tarsal

TAR - SAL (toebone)

[gen2]

humeri

hum + er + 1

PS The other one is HUM -ER -I ...think you have second letter wrong. Good luck, sure you could use a very posh fountain pen.....

Thanks a million guys. She gave me until Casualty finished to see if I could come up with anything, so those really speedy responses were brilliant!
