Yes, I did write it, it's first line is from a lovely hymn I could sing you!

I had goofed and left out an H - so before I add your letters, it should look like this:

In s-eet fields -f a-t--n
The --ld lea-es are fallin-
The d--s -ar- and -hase the-
Th---h their -asters are -allin-

The -ats sit -n -ind--sills
And ta-e in the -ar- s-nshine
All the h-rses -r-- their hea-- --ats
T- prepare f-r --ld -interti-e

All the d--s, -ats, -irds and --nnies
That -e all l--e and treas-re
Are s- -lad f-r their -ar- h--es, n--,
-hen n-rth -ind -rin-s --ld -eather

Which may help you with at least one of the words you're stumped on.

I'll go add your letters and post again in a minute.
