If you lok, you will fid: There's an empty place

Whee the laws of the wld are cmpletely disgraced. 2

In th spring, in this and, the hunting dries out;

And y midsummer's day Hunter's nowhere abou. 4

In the fall, just 'fore dan, he again pokes aound

(Though it' soon that he finds that n hunting be foun). 1

In the wintr he thrives and ool hunting i good,

Though he hunts not in rairie, nor mountin, nor wood. 3

But, alas! on comes spring and he begins to feel umbrage

And again, through the ummer, hibernates in dar slumberage. 1

I think the answer is

Stars

Working off the same logic as Nudge Nudge above (upvote!), the five stanzas yield:

1

L(o)ok, Fi(n)d, Whe(r)e, W(i)ld, C(o)mpletely => Orion

2

th(e), (l)and, (b)y, abou(t) => Belt

3

da(w)n, a(r)ound, it'(s), n(o), foun(d) => Sword

4

wint(e)r, (c)ool, i(s), (p)rairie, mount(a)in => Space

5

(Y)on, (s)ummer, dar(k) => Sky

Then given the words, take the

Indicated letter of each word: O(r)ion, Bel(t), (S)word, Sp(a)ce, (S)ky and rearrange to form STARS, which is of course what Orion's Belt and Sword in Space/Sky are formed of

Partial to kick things off:

The missing letters in each stanza appear to be anagrams:

If you lo(o)k, you will fi(n)d: There's an empty place
Whe(r)e the laws of the w(i)ld are c(o)mpletely disgraced.

ONRIO -> ORION

In th(e) spring, in this (l)and, the hunting dries out;
And (b)y midsummer's day Hunter's nowhere abou(t). 4

ELBT -> BELT

In the fall, just 'fore da(w)n, he again pokes a(r)ound
(Though it'(s) soon that he finds that n(o) hunting be foun(d)). 1

WRSOD -> SWORD

In the wint(e)r he thrives and (w?)ool hunting i(s) good,
Though he hunts not in (p)rairie, nor mount(a)in, nor wood(s?). 3

ESPASW?

But, alas! on comes spring and he begins to feel umbrage
And again, through the (s)ummer, hibernates with dar(k?) slumberage.

SK?
