To discontinue a prosecution the prosecuting attorney files in court a statement known as a _nolle prosequi_, indicating that he does not wish to press the case to trial. The right to do this gives the official a great deal of power, which has been in some cases abused. Footnote 63: A deed is a document by which one person conveys land to another. It is the duty of the purchaser to make sure that his deed is valid and that the seller has a good title to the land which he sells. This he can ascertain by examining the records in the registry of deeds. In some states a plan known as the Torrens System is in operation. Intending purchasers submit their deeds to the registration official, who examines them. If he finds that the title is good, he registers the deed and thereafter the title may not be questioned. Where the Torrens System is not in operation a purchaser can get his title insured by paying a premium to a title insurance company. Footnote 64: There is a widespread impression that the government of the New England towns, being a close approach to a direct democracy, has been a great and consistent success. These towns have been pictured by some writers as little Utopias, free from state interference, and privileged to manage their own affairs in their own way. Unhappily this portrayal does not square with the facts. Small agricultural communities, such as the New England towns used to be, can manage their local affairs satisfactorily under almost any form of government. But when population grows, and factories come in, and local activities are multiplied—then the problems of a town are akin to those of a city and have to be handled in the same way. CHAPTER X CITY GOVERNMENT _The purpose of this chapter is to explain who the city authorities are and what they do._ [Sidenote: To be a city a place must have a charter.]
