Why would you need Sneyer article? The original work for Mann and Kendall may be found at: (1)  Mann, H.B. 1945. Non-parametric tests against trend, Econometrica 13:163-171; and (2) Kendall, M.G. 1975. Rank Correlation Methods, 4th edition, Charles Griffin, London.

HOW TO RUN THE TEST: The step-by-step on how to engage the test may be found here: http://vsp.pnnl.gov/help/Vsample/Design_Trend_Mann_Kendall.htm

REFERENCE: See chapter 12 file attached for further reading on the subject. The author explain quite well.

TREND TEST: you are trying to do trend test. I suggest, looking into various tools for trend test. NIST handbook and website may be useful. See link. Attached is also an article on several trend tests. (see Trend).
