Help with Insignia in 1862 picture

[stratasfan]

Wondering if anyone can help ID anything from the uniform and insignia in this picture! Mom's working on a family history project about a family from Massachusetts. Here is the picture. Would love to know what that uniform and insignia is! :) Thanks! -Elizabeth

Just wearing an “officers style” hunting horn and wreath for infantry and federal style eagle buttons. He sort of looks like a cadet to me.

Here is the writing under the picture:

"Henry Lyman Reed

aged 14 -- 1862

Taken at military school"

That's a very nice image. Do you know where in Massachusetts he lived?  There are a couple of Henry L. Reeds on Fold3 who enlisted late in the war (1864 & 1865) that may be him after he left military school.
