Is there any wrong in this sentence?

...there was a small white boy on a red horse, a small white boy as like to another who had ridden here as any could be.

........

It is in a book I am reading. I can't recall seeing this form before; 'be as like to...'  

I wonder, could it only be an unintentional mistake or something? If no, then please help me to understand it.

Thank you in advance.
