What were the three main inventions considered important in settling with wild west?

Answer 1

Cotton gin, steam engine, pistol.

Answer 2

Peace officers. The town sheriff, and the United States Marshal. Without then, everyone would have been running wild. There were enough outlaws at that time even with the peace officers.
Second, the invention of barbed wire. This allowed cattle owners were able to keep thier seperate form others. Especially, the large cattle barons. This also put a stop to a lot of the cattle stealing.
Third was the steam locomotive. This allowed transport of goods and settlers from other parts of the country. This also brought about a new type of outlaw, the hobo.

Answer 3

Basically the railroad helped to connect many of the towns and settlements to the main world. This allowed the spread of both people and technology.

Also the telegraph allowed the spread of news much faster than conventional mail and the pony express. The telegraph actually put the Pony Express service out of business in 6 months.

Sorry I can't think of the third at the moment

Answer 4

America was settled (after removing the Indians) by imigrants from every corner of the world with one common denominator, "What's for dinner?"
The iron plow of John Deere allowed the turf to be tilled to produce grain and field crops for consumption or as animal feed (excepting grass fodder which grew abundantly allowing free range cattle production )
The introduction of barbed wire (aka the Devils Rope) in 1868 kept those free range cattle from makling incursions on the crops that could now be grown on a greater scale as fencing in the farm became easier than erecting a fence that had to be hog proof around multiple sections of farmland,(P S nothing's hog proof) .
The Iron Horse brought these marketable items to the areas of greatest demand turning the wheat of Kansas in to the Parker House rolls of New York. Those industries still flourish with minor changes in the original insturments of progress that created them.

Answer 5

The railroad, barbed wire and the John Deere cast-steel plough.

The institution of law enforcement made it safe to live there.

The locomotive allowed transportation that connected the vast regions.

Answer 7
