Dracula: Hide-and-Seek

I sometimes think that Dracula would be horrible at playing hide-and-seek. I believe that it would be reasonable to assume that, if a person/man/vampire was forced to rely of 50 boxes of dirt from his own grave site for whatever reason that said person would be extremely careful with where he places them, especially if the person's original tomb is kilometers away across part of an ocean. I also believe that said person would destroy whatever trail he left behind to protect his identity and the location of his precious objects. However, perhaps it is wrong of me to assume that a man with immortal life who has lived centuries on earth, has the wisdom and knowledge to come to an appropriate idea on the best place to hide such valuable artifacts that would aid his life and are important to his essential well-being. After all, if Dracula was not concerned with life, why attempt to hide 50 boxes and not just one? Maybe at this point, he is simply tired of his "half-life" existence and doesn't care about whether or not they would be extremely easy for a small group of people to find, evidenced by the fact that Mina sees in his face upon his death "a look of peace, such as [she] never could have imagined might have rested there.

On the other side of the spectrum, I find myself a little confused as to how the Count's pursuers came to find the precious boxes of earth anyway. It is stated multiple times that the boxes were discovered through research by Johnathan Harker, but I find it hard to believe that in the book's time period there would have been a significant paper trail on objects that would appear so insignificant to anyone who possessed no knowledge of vampires. Maybe I missed it, but perhaps Harker had contacts in the shipping industry?

Despite the outcome of the boxes, Dracula is now extra dead, though perhaps he wouldn't be if he had only taken a bit more care of just one of his boxes of earth.
