Yu Xiaotian then wrote down this matter, and arranged for someone to inform the people of the council hall, so that he would start to purchase a large number of coal from the land in the near future, and vacate a few large ships to be used as coal carriers to transport coal in large quantities to the side of Tamsui.

In addition to coal, the Seawolf's biggest reliance on land is iron and iron ore.

At present, through more than two years of hard work, he has established a supply network for purchasing iron materials on land, continuously absorbing iron materials from the land and transporting them to Tamsui and Nanri Island for storage, and the current reserves are quite large, at least enough for them to use for a year.

For iron ore at present, they do not have much demand, the sea wolf casting cannon and gun are temporarily using raw wrought iron directly purchased on land, which can be used directly, but taking the opportunity, the sea wolf still imported some iron ore, temporarily stored it, and stacked it in a material yard near the freshwater wharf, in short, this thing will definitely not be wasted in the future, and it is better to save silver than to store raw materials.

Although silver is a good thing, it is of little use to Xiaotian, and can only be used as a capital reserve, and no matter how much it is saved, it is not of great use.

Therefore, he has always insisted that the silver in his hand should be purchased immediately into various raw materials, even if they are not needed, they must be stored first, especially some raw materials that they cannot be self-sufficient at present, and they are also related to the people's livelihood and war readiness, which is the focus of procurement.

Among them, copper, iron, saltpeter, and sulfur are naturally the majority, but at the same time, things like sugar, cotton, cloth, and grain are also the focus of the sea wolf's search, but as long as the price is right, they will buy it in large quantities and store it first.

At present, there is a large area in Tamsui City, and many large warehouses have been built to store these production raw materials and living materials.

And the largest warehouse in Tamsui City is probably the grain depot, the grain stored in it, even if it is Tamsui and chicken coops, not a grain of grain a year, it is enough for them to support the past.

However, this also made the sea wolf work for so many years, in fact, there was not much silver stored in the silver treasury, and the silver retained was only used as a reserve, enough to pay the sea wolf for several months, and a large amount of silver earned was replaced with various raw materials for reserves.

At this point, Yu Xiaotian thinks that he is doing a good job, at least he knows better than anyone else, and he must reserve useful things in advance, not silver, because once it is time to use it, there are many times when there is silver and it is not necessarily possible to buy things, but a large amount of silver is saved, and it becomes useless.

Yu Xiaotian personally selected some people who knew this aspect of the matter, scattered to various migrant villages, began to plan ditches and road traffic, and with the help of this canal repair, he also drew a detailed freshwater map, and corrected and supplemented the original map.

Maps are a rare thing in this era, and it takes a lot of manpower and material resources to complete them, and even then, before modern cartography and modern surveying tools, even the maps drawn by masters are very crude and inaccurate.

But this kind of thing is not easy to solve for Xiaotian, Yu Xiaotian only learned a little bit about modern cartography from the textbook, but after a long time, the things he got from the teacher were basically returned to the teacher.

Therefore, he can only let his subordinates use the current means to draw the map as much as possible, but only ask for more detail and accuracy.

In the past, Yu Xiaotian had sent an advance team to draw a map of the area of Tamsui, and had obtained a more detailed topographic map of the area, but after the completion of Tamsui City, with the gradual expansion of the area of the resettlement area, the land was constantly reclaimed and leveled, and the original terrain here has changed to some extent.

In addition, migrant villages are constantly being built, which requires updating, supplementing and modifying the original map to meet their needs.

Therefore, Yu Xiaotian decided to take advantage of the large-scale construction of water conservancy and road construction projects to start this time, and also update the map casually, send more investigation teams to investigate and search outside the resettlement area, and draw a larger map to meet their needs for future expansion here.

Although this is easy to say, but it is difficult to do, now the settlement area of Tamsui City is quite large, and the terrain is relatively complex, this is not a plain area, but mostly hilly terrain, and there are more streams in this area, and the water resources are relatively rich.

However, even so, if the ditch and drainage road are not planned in advance, once the construction begins, the irrigation and drainage ditch will not only not work, but may have a negative impact.

Therefore, the trend of the ditch and the location of water diversion and drainage, it is necessary to choose a good one, in addition to the height difference of the terrain, but also to have at least one understanding, before the construction, as far as possible to plan, so as not to make too many mistakes, when the ditch is excavated, but can not introduce water into the ditch, then the work will be done in vain.

Therefore, although Yu Xiaotian was in a hurry, he did not dare to start the construction rashly, but first sent people to do this thing, planned the ditch channel road first, and only after doing this well could he start to organize the construction.

As for the construction manpower, Yu Xiaotian decided to dig the ditch and use the labor of each migrant village on the spot to carry it out, and the specific organization was carried out by each township and village, and the sea wolf was only responsible for providing certain tools to meet their needs.

The reason for this is because Yu Xiaotian feels that when it is time to be good for immigrants, it must be good, but he can't get used to them, because the water conservancy project is a project that directly benefits them, once it is repaired, they are the first beneficiaries, and after having water conservancy ditches, their farmland can be watered in the dry season, and the excess rainwater can be drained in the rainy season, so that they can get direct benefits from it.

Therefore, if this kind of thing is all borne by the sea wolf, it will be too much, so this water conservancy project needs the immigrants from each village to work and contribute their own efforts to complete, and when necessary, the sea wolf can organize manpower and material resources to help.

Of course, for the immigrants who have just come here, they have not yet gained a foothold, there is no harvest, and the problem of food has not been solved, and the food supply will naturally be borne by the Seawolf Group, otherwise the ditch will not be dug out, and these new immigrants will probably starve to death, and no one will do this.

But for the matter of building roads, Yu Xiaotian decided to let the Seawolf Group bear it, because if the immigrants are allowed to dig ditches and also undertake road repairs, the amount of work that the immigrants have to undertake is too large, and now is the spring ploughing period, and the immigrants have to cultivate and build roads at the same time as building water conservancy, which may affect the harvest of this year and seriously affect the work of spring ploughing.

And the road repair thing, and can not be delayed to the time of farming, because when the ditch is excavated, it will inevitably be staggered with the road, and the excavation of the ditch will take out a lot of earthwork, these earthworks can just be used to repair the road, if you miss it, you will have to use manpower and material resources for the second time in the future, which will cause waste and loss of human and financial resources.

In addition, since ancient times, the construction of roads has basically to rely on the local government to organize and invest, to complete, only by the people themselves, at most is to build some country roads or farmland roads, like this kind of road network that connects the entire resettlement area, want to rely on immigrants to build, obviously inappropriate.

This is also a cost that the sea wolf must pay, and this kind of investment, for the sea wolf will also recover the cost, in the future the migrant village pioneer farmland output of food, the sea wolf is to charge 30%, as a food to meet the needs of the sea wolf itself, although the road benefits the immigrants, making it much easier to travel, but at the same time it is also conducive to the sea wolf to strengthen the ability to control their own territory, the road is their future effective control of these migrant villages of the weapon.

Therefore, Yu Xiaotian decided that the sea wolf would be responsible for the construction of the road, and in terms of labor, he would mainly use the purchased slaves and the laborers of the original hard labor camp here.

For this kind of project that requires a large amount of labor input, the amount of labor in the road itself is very large, and the labor intensity is also very large, and now there is no modern construction machinery that can be used, all of them must be completed by manpower and animal power, and even animal power is seriously insufficient, spring ploughing should occupy a large number of ploughing cattle and animal power, so basically all rely on manpower to complete, so that it is inevitable that there will be some casualties, immigration is the basis that Yu Xiaotian relies on in the future, not can be used casually to consume, But for these slaves and slaves, it was worthless.

Therefore, during the period of sanitation rectification, Yu Xiaotian also arranged for the repair of canals and roads, and asked the township chiefs and village chiefs of various townships and villages to go down to do the preliminary mobilization work, and began to allocate tools to make various stones and vehicles for road repair.

Stone is easy to do, the most important thing in Taiwan is stone, especially the marble reserves are extremely rich, and now Tamsui City has its own quarry, there are also many stonemasons, carved dozens of such big stones do not take much effort.
