The beginning of a well known book has been encrypted below. Each letter of the alphabet has been replaced by another using a simple substitution technique. For example, A may always be represented by G, etc. Can you name the book?

The piece of text is from the original book and should read:
The first place that I can well remember was a large pleasant meadow with a pond of clear water in it. Some shady trees leaned over it, and rushes and water-lilies grew at the deep end. Over the hedge on one side we looked into a ploughed field, and on the other we looked over a gate at our master's house, which stood by the roadside; at the top of the meadow was a grove of fir trees, and at the bottom a running brook overhung by a steep bank.
While I was young I lived upon my mother's milk, as I could not eat grass. In the daytime I ran by her side, and at night I lay down close by her. When it was hot we used to stand by the pond in the shade of the trees, and when it was cold we had a nice warm shed near the grove.

Hint: It's not just the vowels that have a problem.
Answer: H, S and T.
It should read:
Can you tell what is wrong with this paragraph? At first glance you may think that just the vowels have problems, but no! Three consonants also have problems, they have been replaced with the letter R, but which ones are they?
Each number in the sequence is a representation of the number 32 in different bases, starting with base 10.
Base 10: 32 = 3 x 10^1 + 2 x 10^0 = 3 x 10 + 2 = 32
Base 9 : 35 = 3 x 9^1 + 5 x 9^0 = 3 x 9 + 5 = 32
Base 8 : 40 = 4 x 8^1 + 0 x 8^0 = 4 x 8 + 0 = 32
Base 7 : 44 = 4 x 7^1 + 4 x 7^0 = 4 x 7 + 4 = 32
Base 6 : 52 = 5 x 6^1 + 2 x 6^0 = 5 x 6 + 2 = 32
Base 5 : 112 = 1 x 5^2 + 1 x 5^1 + 2 x 5^0 = 1 x 25 + 1 x 5 + 2 = 32
Base 4 : 200 = 2 x 4^2 + 0 x 4^1 + 0 x 4^0 = 2 x 16 + 0 + 0 = 32 (as required)
During a recent Formula 1 race meeting, Sterling managed to complete a lap with an average speed of 150 mph. He managed to complete the first two fifths of the lap length at a speed of 123 mph and the second two fifths of the lap length at a speed of 164 mph. At what speed was the final one fifth of the lap length covered - the answer is not 176 mph?
we have had a lot of queries on this puzzle and many methods have been suggested but only the one below gives the correct answer.
If we take the number of miles in a lap to be x miles and using time = distance / speed.
The first 2/5 are covered at 123 mph. Therefore, the time taken was [(2/5) * x] / 123 hours.
The next 2/5 are covered at 164 mph. Therefore, the time taken was [(2/5) * x] / 164 hours.
The last 1/5 is covered at y mph. Therefore, the time taken was [(1/5) * x] / y hours.
The entire trip is covered at an average of 150 mph. we can conclude that:
2x 2x x x
----- + ----- + --- = ---
5*123 5*164 5*y 150
Working this out we get:
1 -2 -2 1
-- - --- - --- = -
30 123 164 y
The means that y = 1 / (1/30 - 2/123 - 2/164)
Therefore y = 205.
