Understanding a pattern

I just have a question on understanding a pattern. Here is how it reads: work 45 rows in garter stitch
Inc 8 sts at the beginning of the next 8 rows(109sts
Cont straightfor 26 rows, ending with right side facing for the next row.

HELP!!

Welcome to KH!
Can you give us a link to the pattern or a pattern name, please?

The pattern probably wants you to cast on 8sts at the beginning of the next 8 rows. You can use a knit or a cable cast on for this. Here’s a video that shows you how in case you need it.

I found some Songbird patterns on Ravelry but perhaps not the one you’re making:
