The author alleges in the letter that because of the smaller number of users of the library in Polluxton (PO for short), a suitable way to economize and improve service is to clsoe the library in PO. To support this suggestion, some facts of garbage collection departments are utilized. Both the facts and the reasoning process, nevertheless, suffer a number of serious logic fallacies, leaving the conclusion dubious.

First of all, it is the example of trash collection departments in PO and Castorville (CA for short) that the reasoning bases on. In this example, however, no trustworthy evidences are capable of telling that the merge had actually either improved service or saved money. That few complaints about the new department were reported, it is too hasty to declare that citizens were satisfied with the service, since it may the case that to complain to the department is of no use or in which way habitants could make a complaint was unclear.

Secondly, an analogy has been assumed between the garbage collection department and library, which is doubtful. In reality, the reason for which readers were fewer in PO is not shown, neither is the average number of users there. Whether the decrease in quantity of users last year is representative, or just because a large augmentation turned up during the previous year does make a difference. Moreover, how many does the '20 percent' stands for is important to know, for generally, 20 percent of one million is surely a considerable total, while 20 percent of ten is only seven.

What is more, it is problematic to conclude that it is now necessary to further economize and improve service in the same way as that of garbage collection. The situation of library in CA is not clear, as a result of which it is not reasonable to close the library in PO, leaving the one in CA.

As a conclusion, the tantalizingly plausible approach to save money and improve service is doubtful, because of the logic drawbacks in the reasoning. To support the essay, more details are in need.
