I have checked the script for the answer and it seems the Witch hurls a fire ball at the scarecrow and then Dorothy throws a bucket of water over him also covering the witch which melts her.
Please see the script below for this dialog:
Scarecrow
Hurry, we've got no time to lose!
Wicked Witch
Ha, ha, ha! Going so soon? I wouldn't hear of it. Why, my little party's just beginning.
Ha, ha, ha, eh, eh!Ring around the Rosey! A pocket full of spears! Well,
the last to go will see the first three go before her! And your mangy little dog, too!
How about a little fire, Scarecrow? Huh?
Scarecrow
No! No! No! No! Help! I'm burning! I'm burning! I'm burning!
Wicked Witch
No, don't throw that water! Ohhhhh! You cursed brat! Look what you've done! I'm melting!
Melting!
Leader of Winkies
She's - she's dead. You've killed her. Hail to Dorothy! The Wicked Witch is dead!

It was all due to the savage and wicked winter of 1885-86 that killed thousands upon thousands of cattle due to overgrazed rangeland and no winter feed. Barbed wire fences where only a minor problem compared to the wicked force of Mother Nature and Old Man Winter. The decline of the cattle kingdom was brought upon by many things. With manifest destiny bringing people into the west, cattle were merely outnumbered and there were just less to be moved. Also, cattle were being mass produced enough to meet the demand of the people, so jobs were temporarily slowed.
