The (almost really) Complete Works of Lewis Carroll

Is it the glow of conscious pride

Source: The New Belfry (extracted)

Is it the glow of conscious pride—
Of pure ambition gratified—
That seeks to read in other eye
Something of its own ecstasy?
Or wrath, that worldlings should make fun
Of anything ‘the House’ has done?
Or puzzlement, that seeks in vain
The rigid mystery to explain?
Or is it shame that, knowing not
How to defend or cloak the blot—
The foulest blot on fairest face
That ever marred a noble place—
Burns with the pangs it will not own,
Pangs felt by loyal sons alone?
