One way ..

Assuming the 31 sheets are named sequentially as:
Sheet1, Sheet2, ... Sheet31

and the average figures in each sheet are in row 26,
viz. in: A26, B26, C26 ... Z26 etc

In a sheet: Summary (say)
----------
List the sheetnames down in say, A2:A32,
i.e.: Sheet1, Sheet2, ... Sheet31

Put in B2:
=OFFSET(INDIRECT("'"&$A2&"'!A1"),25,
COLUMNS($A$1:A1)-1)

Copy B2 across as many cols as there are figures to be pulled over from each
sheet, then fill down to row 32

The above will extract the results that you're after

We do hourly analyses of water covering five items, like pH, iron,
sulphate
temperature, etc. We have 30 or 31 sheets (1 sheet for every day of the
month) with 24 hour rows with averages of each analysis at the end, i.e.
the
average of the day's analysis per column. I want to have a separate sheet
with every day's average for each item tested for. How do I enter the
items
average from each sheet without doing it manually by entering = and then
going to the sheet and the reading and clicking it.
