hemlocks

An insect that feeds on hemlocks; its egg sacs are small fuzzy white balls like artificial snow on a Christmas tree.

以铁杉为食的昆虫；其卵囊为有绒毛的小白球，形似圣诞树上的人造雪。

trees thickened around him, oaks and poplars, some hemlocks.

周围的树木很繁茂，橡树、杨树还有铁杉。

these hemlocks whispered over his head, these hickory logs were his fuel, and these pitch pine roots kindled his fire;

铁杉在樵夫的头上耳语，山核桃是他的燃料，还有松脂的松根供他点火；

although both feed by draining the hemlocks of their juices, the adelgids also inject toxic chemicals into the trees.

虽然它们都依靠吸铁杉的树汁存活，但球蚜同时还把有毒的化学液体注进了树木。

this is great smoky mountains national park, and the hemlocks are dead as far as the eye can see.

这是大烟山国家公园，而眼睛所及之处的铁杉均已死去。

or was it a cry against the hemlocks?

或者，那是对抗铁杉的叫喊？
