Here you will find the Poem A Calendar of Sonnets: September of poet Helen Hunt Jackson
O golden month! How high thy gold is heaped! The yellow birch-leaves shine like bright coins strung On wands; the chestnut's yellow pennons tongue To every wind its harvest challenge. Steeped In yellow, still lie fields where wheat was reaped; And yellow still the corn sheaves, stacked among The yellow gourds, which from the earth have wrung Her utmost gold. To highest boughs have leaped The purple grape,--last thing to ripen, late By very reason of its precious cost. O Heart, remember, vintages are lost If grapes do not for freezing night-dews wait. Think, while thou sunnest thyself in Joy's estate, Mayhap thou canst not ripen without frost!
