I saw a hound,an enormous black hound.it was bigger than any dog i had ever seen.but it was something else that filled us with terror.no human eye had ever seen a hound like this one.fire came from its open mouth.its eyes were burning.flames covered its head and body.it was a more horrible sight than anyone could imagine-a hellhound sent by the devil.it was not a creature of the natural world.

我看到了一只猎犬，一只大的、黑色的猎犬。它比我所见过的任何狗都要大。可是，是别的原因才使我们充满恐惧之情的。任何人都未见过与此类似的猎犬。火从它那张着的嘴巴里喷了出来。它的眼睛亮得像冒火一样。头和躯体都由火焰笼罩着。这是一幅比任何人的想像所及还要恐怖的景象--一只由从恶魔派来的地狱看门犬。它不是自然界的一个生灵。

The first part took temperature,moisture,pH and C/N ratio as the main technological index to make sure the befit compost condition of quantity of inoculant, moisture,pH and C/N ratio.
