Mastodon
Mastodons (Greek: μαστός "breast" and ὀδούς, "tooth") are any species of extinct mammutid proboscideans in the genus Mammut, distantly related to elephants, that inhabited North and Central America during the late Miocene or late Pliocene up to their extinction at the end of the Pleistocene 10,000 to 11,000 years ago. Mastodons lived in herds and were predominantly forest dwelling animals that fed on a mixed diet obtained by browsing and grazing with a seasonal preference for browsing, similar to living elephants.
M. americanum, the American mastodon, is the youngest and best-known species of the genus. They disappeared from North America as part of a mass extinction of most of the Pleistocene megafauna, widely presumed to have been related to overexploitation by Clovis hunters, and possibly also to climate change.
Description
Mastodon (steam locomotive)
Mastodon was the unofficial name of the Central Pacific Railroad's number 229, the world's first successful 4-8-0 steam locomotive.
History and career
The engine was designed and built by the road's master mechanic, Andrew Jackson "A.J" Stevens at Sacramento Locomotive Works in 1882. The locomotive had two highly unusual features: the firebox shape and the steam distribution.
The special valve gear operated four slide valves for each cylinder, two of which were worked by Stephenson valve gear, but used for reversing only, and two more, on top of the first two, for controlling the cutoff, these being operated by a third eccentric through a rocking lever with a sliding block on one arm. The use of a double valve gear is reminiscent of Centipede, but separate valves for each end of the cylinder were novel on a locomotive. This valve gear gave very good steam distribution even at short cut-offs; short as understood for a saturated-steam engine with a boiler pressure low by modern standards. At long cut-off and a speed of 8 miles per hour (13 km/h) the indicated mean effective pressure was 124 lb/sq in (8.7 kg/cm2; 850 kPa), which is over 91 per cent of the boiler pressure of 135 lb/sq in (9.5 kg/cm2; 930 kPa), that is to say more than the 85 per cent normally used to calculate the tractive effort at starting.

Stargasm
by: Mastodonthe temple of bodies.
a building of souls.
Given the cosmos.
as we let go. as we let go.
locked in a dance.
surrounding the moon.
this far from the clouds.
stargasm flows
Stargasm
lead us by horses.
on the wat to our graves.
father the owl.
it is your faith. is it your faith.
awake in the moment.
awaken the heart.
look to the spirts.
stargasm glows
stargasm
and then we shift into overdrive.
but you're not here.
and your legs and the stars collide.
you're on fire. you're on fire. you're on fire.
hanged from the solstice.
bohemian grove
fresh lies the alter.
as we let go. as we let go.
glasses are empty.
the owl has flown.
sever relation
like you didn't know. like you didn't know.
and then we shift into overdrive.
but you're not here.
and your legs and the stars collide.
