Overall, the source mentions some of the impacts of the war on Scottish industry and the economy, but it misses out several key factors, such as.The source omits how there were many employment opportunities in the textiles industry as uniforms were required for soldiers on the Western front. This makes the source less useful as it fails to mention a key economic impact of the war.The source also omits how there were huge gains in the forrestry industry as a result of the war. Huge quantities of timber were required for constructing trenches, and other buildings, on the western front. So, missing a major economic change makes the source less useful. Finally, the source misses out how coal mining was massively benefited from the war. Huge quantities of coal were required to power warships, and trains which were increasingly used for transporting supplies. Missing out this economic impact makes the source less useful.However, the source does mention how "1,008,100 8-inch shells" were produced in Cardonald during the war. This is a huge amount of ammunition which could have employed the entire surrounding area. The impact on the surrounding towns of these factories was enormous, so the source is useful for showing this economic impact.The source also says how "15 national projectile factories" were to be built to produce more ammunition for the war effort. There would have been major employment opportunities for engineers who could build these factories. Thus, the source correctly identifies a major economic boon from the war. Overall, the source is only partially useful as it omits more economic impacts than it contains, but still has some valuable insights.
