Dorothy, Scarecrow, and Toto bring a donkey and cow (played by Men In Suits) along with them in the cyclone (which is simulated by having them hug a big hay bale that turns around and around).
ALL THE INTERTITLES ARE IN GIANT BLOCK CAPITALS.
Toto is a real dog who turns into Man In A Suit #3 to fight the lion (Man In A Suit #4), who is not cowardly at all.
There is a line of chorus girls and another of palace guards. At the end, the guards ride in on REAL HORSES, which makes the Men In Suits (by now including #5, bug, and #6, frog, from the Wicked Witch's lair, and #7, kitty cat, who otherwise has no apparent role in the action) look really, really lame.
The cast of thousands and elaborate sets make you wonder why no one had yet thought of MULTIPLE CAMERAS, and EDITING. But that was a concept they obviously couldn't wrap their minds around, back in 1910. Who knows - maybe a second camera would have cost more than all the actors, dancers, horses, and animal costumes put together.
