You have created a line of general purpose farming equipment powered by people, seeing as you have not developed any form of engine to do so. This is very useful for farmers, and mass production is started. The amount of farmers required in an arbitrary area of farmland goes down, and these people who are unemployed go into the industrial workforce. Still would be much better if people weren't powering the stuff, and some more reliable method was found.
You found that the farmers have been taking a portion of their food to feed their families. This is heresy! We don't have enough food for the industrial workers, who are much more numerous. Sadly, now the farmers are starving. This will likely cause people to stop farming and go work in the industries, making the problem worse. Heavy industrial production is going swimmingly, except for the well known shortages of everything. People are mad... I'd start preparing...

The parallels between this and real life are pretty impressive. You know why the Russians have had the best ballet? You take all the people who are good at ice skating and force them to do ice skating their entire life, from birth. They do not matter as people.
Yours is not that harsh, but still. The people who are good at learning will be put into the bigger better schools. I cringe where people would put me, a person who thrives upon individualism and free thought. I doubt there is a school for that. A lot of parents are sad for this, and decline the offer of better education due to the fact that they'll have to travel, and the quality of this education is still pretty bad. Like teaching pretty basic math bad. Even the selection process is pretty bad. You gotta account for those people who look dumb but are really surprisingly smart. The results of this are minimal, but it provides the foundation for something greater.
In other news, people are not traveling to the amusement park city. Too far out of the way. I'm not going to spend a week traveling for a day's worth of fun. A lot of this has to do with the slowness of horse and buggy. Maybe a railroad would help.
You put out a subsidy for fishing, this does attract more people to fish, but people already were to begin with. And I'm talking going out on a boat fishing, not just sitting at the dock and throwing a hook and hoping for a catch. The middle class is getting in on it though, and now it is "in fashion" for people who own a boat to go out and fish for fun, then make a quick buck with the haul.

You have designed a new light artillery piece, still direct fire, but now with longer range. Longer barrel --> more range and better accuracy, but lower muzzle velocity.
You have developed a standardized steam engine. It is industrial sized, made to be used in larger boats. This is due to a distinct lack of oil. Note, you do know of internal combustion, it is simply not used everywhere cause not everywhere has it/is currently using it as a method of power.
Due to the method of the design, it is possible to outfit the boat with the new inventions. In total, 10 Dandalo A Class gunboats are produced with two 90mm guns, and powered by a steam engine. Over time, this should increase with continuation of this order. The more ships you produce, the better you get at making ships. You might want to develop a better engine though, as your steam engine is inferior to internal combustion power. Also, you might want to ask Nev for rights to drill oil, as currently while they have oil, it is not being mined.
Low Lands
Construction of a railway from coast to coast has begun with the approval of the German states. Unfortunately, said German states want it to go through each of them. Like right then south, instead of directly south through Italia. Should be profitable, but it would delay completion. They want a final word on it before it happens. This will effect your standing with the German states. Production of the railway in the Lowlands is beginning though.
A series of trenches have been constructed on the border of Rordalia. They are manned by a bunch of volunteers. Sadly, you don't have a very good army to work with, and volunteers is the best you got. Yes, you do have some careerist military people, but they're held in reserve by the military leaders. Let the poor people die first.
You send a fresh batch of volunteers and missionaries to the colony. Hopefully they'll expand it. I doubt it. You don't want to know what is happening down there. Nobody wants to live there. It is horrible.
Rordalia
Fgerbia does not accept this alliance because they don't see it as feasible. You are so far away. It would be like Nev promising to aid the people of Australia. everyone else acknowledges that you are protecting Fgerbia, except for Fgerbia, who sees it as a proposition that is only for Rordalian interests.
The first batch of underwater explosives are working well, now the only thing is to find a method of propulsion for them, or to just produce them and deploy them places as mines.
Railroad construction to improve agriculture is going well, but it is also cutting into the life style and culture of the cowboys, people who would move cattle from place to place for low pay. It is a pretty big part of Rordalian culture. Still it is dangerous, and the railroads are better, just life is moving from the open plains to the closed off plains.
The railroad is directed to have an ending section near the border, to allow the Lowlanders to connect it if need be. This would provide the ability for either side to send across armored trains mounted with weapons for a quick breakthrough but also make a pretty good profit.
Scandanavia
A new unit of infantry is created, filled of the more elite careerist troops, to act in small squads. They will work behind the lines, around the lines, whatever.
A unit of espionage has been created. Maybe this will leak plans. We know that Rordalia threatened someone, just not who. Like the thought that a menacing message may have been intercepted going from Rordalia to Italy, judging by their immediate turn in diplomatic stance from one of nationalism to one of cooperation and passiveness. And they also clarified their stance to be anti imperialist. Currently nobody is doing anything in secret, as far as you know.
With a basic consumer industry up and running, the process of creating heavy industry has begun similarly to the lighter consumer industry. People are still annoyed cheap imports hurting the economy, but cheap imports are also helping the economy as well. We'll see what happens.
