TWO RIDDLES

1)

Bound in a book that can't be read,

Your equal in skill and stature,

Heat and light I manufacture.

 

2)

I'm a word of six letters,

My first three a young man,

My last five a snake;

My second, third, and fourth,

What you must do to find a sum.

My whole a device

That will increase your height.
